 поведения "std::from_chars", но он к сожалению очень ограничен
 по возможностям. Здесь я попытался произвести тесты, близкие по
 логике к работе std::from_chars
+In simstr, a string fragment is sufficient for conversion to a number;
+there's no need for null termination. The closest analog to this behavior
+is "std::from_chars," but unfortunately, it is very limited in its capabilities.

+signs, spaces, 0x prefixes, etc.

-## Что было и есть
-Во вступительной части я хочу немного описать, каково ныне состояние со строками в С++, как мы к нему докатились и почему оно таково.
-А также описать недостатки текущих реализаций, чтобы были понятны решения, которые я использую в своей библиотеке строк.
+## What was and is
+In the introductory part, I want to briefly describe the current state of strings in C++, how we got to it, and why it is so.
+I will also describe the shortcomings of current implementations so that the solutions I use in my string library are clear.
 
-Собственно, изначально как такового стандартного типа для строк в С++ не было.
-Для работы со строками использовался подход из C – строка есть указатель на массив байтов, оканчивающихся нулём.
-Недостатки таких строк — невозможно в строке использовать байт `0`, т. е. не подходит для бинарных данных,
-непонятна стратегия управления/владения ресурсами, ну и основной недостаток — длину строки приходится вычислять каждый раз,
-перебирая все её символы.
+Actually, initially there was no standard type for strings in C++.
+The approach from C was used to work with strings – a string is a pointer to an array of bytes ending in zero.
+The disadvantages of such strings are that it is impossible to use the byte `0` in the string, i.e. it is not suitable for binary data,
+the resource management/ownership strategy is unclear, and the main disadvantage is that the length of the string has to be calculated each time,
+iterating over all its characters.
 
-Откуда ноги растут у такого решения вполне понятно — со времён динозавров: как динозавры были большие, с маленьким мозгом и
-короткими ручками, так и компьютеры были большие, память у них была маленькая, а строки короткими. Сэкономить память на хранении длины строки было важнее, чем потерять время на повторный подсчет длины.
+The origin of this solution is quite clear – from the time of the dinosaurs: just as dinosaurs were large, with small brains and
+short arms, so computers were large, memory was small, and strings were short. Saving memory on storing the length of a string was more important than losing time on repeatedly calculating the length.
 
-Первые попытки стандартизировать строки как класс начались только в С++98 - std::string появился, как часть STL, и как
-многое из STL, крайне неоднозначно воспринимался программистами.
+The first attempts to standardize strings as a class began only in C++98 - std::string appeared as part of STL, and like
+much of STL, it was extremely ambiguously perceived by programmers.
 
-И первое, что приходит в голову при улучшении C-строк — надо хранить длину строки:
+And the first thing that comes to mind when improving C-strings is that you need to store the length of the string:
 ```cpp
     struct simple_string {
         const char* data;
@@ -32,92 +33,92 @@
     };
 ```
 
-При наличии такой строки, уже множество алгоритмов значительно оптимизируются.
-Например, при сравнении двух строк на равенство мы можем даже не начинать сравнивать их символы, если длины строк не равны.
-Более того, этих данных абсолютно достаточно для всех методов, которые не модифицируют строку.
-Также заметим, что такой объект на современных 64-битных архитектурах прекрасно передается в функции по значению —
-оба его поля укладываются в регистры (ну, кроме windows), что облегчает работу оптимизатору компилятора.
+With such a string, many algorithms are significantly optimized.
+For example, when comparing two strings for equality, we may not even start comparing their characters if the lengths of the strings are not equal.
+Moreover, this data is absolutely sufficient for all methods that do not modify the string.
+Also note that such an object on modern 64-bit architectures is perfectly passed to functions by value –
+both of its fields fit into registers (well, except for Windows), which makes it easier for the compiler optimizer to work.
 
-Между тем, такое решение попало в стандарт только аж в С++17, в виде `std::string_view`.
-Видимо, только тогда до комитета смогли донести мысль, что строки строкам рознь, и использовать только один универсальный объект
-для строк — по меньшей мере может приводить к уменьшению производительности, а также нарушает принцип «не плати за то,
-чем не пользуешься». Почему же «строки строкам рознь» и почему нам мало одного типа для строки, рассмотрим как раз далее.
+Meanwhile, such a solution only made it into the standard in C++17, in the form of `std::string_view`.
+Apparently, only then could the committee be convinced that strings are different, and using only one universal object
+for strings – at the very least, can lead to a decrease in performance, and also violates the principle of "don't pay for what you
+don't use". Why are "strings different" and why is one type of string not enough for us, we will consider just below.
 
-### Ресурсы
-И следующий вопрос, возникающий со строками — это владение ресурсами.
-Практически каждый крупный фреймворк решал эту задачу самостоятельно, изобретая свои велосипеды.
-У нас есть `std::string`, в QT у нас `QString`, в MFC - `CString`, в ATL - `CAtlString`, свои строки есть в Folly,
-в общем, “тысячи их”, любой игровой движок начинают с того, чтобы написать свои строки.
+### Resources
+And the next question that arises with strings is resource ownership.
+Almost every major framework solved this problem on its own, inventing its own bicycles.
+We have `std::string`, in QT we have `QString`, in MFC - `CString`, in ATL - `CAtlString`, there are own strings in Folly,
+in general, "thousands of them", any game engine starts with writing its own strings.
 
-Многие из этих реализаций в аспекте управления ресурсами для улучшения производительности использовали подход
-**COW** – “Copy On Write”. При этом объект строки ссылался на некий разделяемый между несколькими объектами буфер с символами
-строки и счётчиком ссылок на этот буфер, что позволяло быстро создавать копию строки, а реально копировать символы только
-при её модификации.
+Many of these implementations in the aspect of resource management used the approach to improve performance
+**COW** – “Copy On Write”. In this case, the string object referred to a buffer shared between several objects with the characters
+of the string and a reference counter to this buffer, which allowed you to quickly create a copy of the string, and actually copy the characters only
+when it is modified.
 
-Но все они совпадали в одном — строка всегда предполагалась мутабельной, то есть что мы можем модифицировать символы в буфере строки.
+But they all coincided in one thing – the string was always assumed to be mutable, that is, we can modify the characters in the string buffer.
 
-### Мутабельность / иммутабельность
-Из-за этого подход **COW** умер к С++11: при каждой операции, могущей модифицировать символы строки приходилось проверять,
-не ссылаемся ли мы на разделяемый буфер и если да, то копировать символы в другой буфер.
-В многопоточной же среде потом ещё и проверять, не надо ли теперь освобождать старый буфер, и естественно всё это обмазавшись
-локами или атомиками, что тоже не бесплатно.
-Поэтому, начиная с С++11 `std::string` не использует **COW**, и каждое копирование объекта строки приводит и к копированию
-всех символов строки в другой буфер.
+### Mutability / immutability
+Because of this, the **COW** approach died by C++11: for each operation that could modify the characters of the string, it was necessary to check
+whether we are referring to a shared buffer, and if so, copy the characters to another buffer.
+In a multithreaded environment, you also need to check whether you now need to free the old buffer, and of course, all this is smeared with
+locks or atomics, which is also not free.
+Therefore, starting with C++11, `std::string` does not use **COW**, and each copying of a string object also leads to copying
+all the characters of the string to another buffer.
 
-Естественно, что каждый новый буфер требует аллокации памяти, что пытаются немного оптимизировать за счёт **SSO** –
-“Small String Optimization”, когда объект строки содержит внутри себя небольшой буфер и символы коротких строк
-располагаются прямо в нём.
-Но это уже зависит от реализации:  в одних библиотеках помещают в объект строки до 15 байт, в некоторых до 23.
-Однако эта оптимизация тоже палка о двух концах, и может в различных реализациях усложнить перемещение строки - если она хранит
-указатель на свой внутренний буфер, его придётся корректировать.
+Naturally, each new buffer requires memory allocation, which they are trying to slightly optimize through **SSO** –
+“Small String Optimization”, when the string object contains a small buffer inside itself and the characters of short strings
+are located directly in it.
+But this already depends on the implementation: in some libraries they place up to 15 bytes in the string object, in some up to 23.
+However, this optimization is also a double-edged sword, and in various implementations it can complicate the movement of a string - if it stores
+a pointer to its internal buffer, it will have to be adjusted.
 
-А без COW мутабельность строк приводит к тому, что любая инициализация объекта строки приводит к копированию байтов.
-Посмотрим такой код:
+And without COW, the mutability of strings leads to the fact that any initialization of a string object leads to copying bytes.
+Let's look at this code:
 ```cpp
-    const char* text1 = "Hello, World";         // ничего не стоит
-    std::string_view text2 = "Hello, World";    // Ничего не стоит, вычисляет длину строки при компиляции
-    std::string text3 = "Hello, World";         // В рантайме каждый раз копирует символы строки
+    const char* text1 = "Hello, World";         // costs nothing
+    std::string_view text2 = "Hello, World";    // Costs nothing, calculates the length of the string at compile time
+    std::string text3 = "Hello, World";         // Copies the characters of the string every time at runtime
 ```

-Но если нам дальше по коду не нужно никак модифицировать строку, мы зря платим за аллокацию, копирование символов,
-а также за деструктор строки. То есть хотелось бы иметь как минимум два варианта строк — мутабельные и иммутабельные,
-чтобы явно дать понять компилятору, что мы не собираемся модифицировать строку.
-Или банальный пример — мы парсим какой-то входящий буфер данных, нам нужно проверить, равен ли некий кусок буфера строке
-”hello” на «чистом С++», т. е. без всяких memcmp и strcmp. До появления string_view приходилось делать примерно так:
+But if we don’t need to modify the string in any way further in the code, we are wasting money on allocation, copying characters,
+as well as on the string destructor. That is, I would like to have at least two versions of strings – mutable and immutable,
+to explicitly make it clear to the compiler that we are not going to modify the string.
+Or a banal example – we are parsing some incoming data buffer, we need to check whether a certain piece of the buffer is equal to the string
+"hello" in "pure C++", i.e. without any memcmp and strcmp. Before the advent of string_view, it had to be done something like this:
 ```cpp
     bool is_part_buffer_equal_hello(const char* data, int start, int end) {
         return std::string(data + start, end - start) == "hello";
     }
 ```
-Тут получается, сначала копируются символы из буфера data в буфер временной строки, возможно с аллокацией памяти, и лишь
-потом временная строка сравнивается с ”hello”, а потом ещё и деструктор и раскрутка стека на случай исключения.
+Here it turns out that first the characters from the data buffer are copied to the buffer of the temporary string, possibly with memory allocation, and only
+then the temporary string is compared with "hello", and then also the destructor and stack unwinding in case of an exception.
 
-При использовании же вместо `std::string` `std::string_view` – код на C++ почти не меняется:
+When using `std::string_view` instead of `std::string` – the code in C++ almost does not change:
 ```cpp
     bool is_part_buffer_equal_hello_view(const char* data, int start, int end) {
         return std::string_view(data + start, end - start) == "hello";
     }
 ```
-Однако генерируемый машинный код значительно преобразуется, достигая уровня ручного С-кода — там просто сравнивается,
-что end – start == 5 и дальше кусок начального буфера сравнивается через memcmp со строкой ”hello”
-(при -O2 c константами 1819043176 (’hell’) и 111 (’o’)).
-Ни создания временного объекта, ни копирования байтов, ни деструктора, ни раскрутки стека для исключений.
-Убедится можно на https://godbolt.org/z/9fo188e7c
+However, the generated machine code is significantly transformed, reaching the level of manual C-code – there it is simply compared
+that end – start == 5 and then a piece of the initial buffer is compared via memcmp with the string "hello"
+(with -O2 with constants 1819043176 ('hell') and 111 ('o')).
+No creation of a temporary object, no copying of bytes, no destructor, no stack unwinding for exceptions.
+You can verify this at https://godbolt.org/z/9fo188e7c
 
-Казалось бы, ну вот же в С++17 появился `string_view`, пожалуйста, используй его в параметрах своих функций вместо `const std::string&`,
-и будет счастье. Но тут тоже есть нюанс — всё отлично работает, пока нам не нужно передать строку в стороннее C-API: string_view не даёт
-гарантий нуль-терминированности строки, поэтому его data() нельзя передать в стороннее C-API, и потому всё-равно придётся сначала
-скопировать его в `std::string`. А раз нужен `std::string`, то и параметром функции оптимальнее cделать `const std::string&`
-и далее по цепочке, все параметры вновь станут `const std::string&`.
+It would seem, well, `string_view` appeared in C++17, please, use it in the parameters of your functions instead of `const std::string&`,
+and there will be happiness. But there is also a nuance here – everything works fine, as long as we don’t need to pass the string to a third-party C-API: string_view does not give
+guarantees of null-termination of the string, therefore its data() cannot be passed to a third-party C-API, and therefore you will still have to
+copy it to `std::string` first. And since `std::string` is needed, then it is more optimal to make `const std::string&` the parameter of the function
+and further down the chain, all parameters will again become `const std::string&`.
 
-### Конкатенация строк
-Далее, после инициализации строки, самая частая мутабельная операция с ними, скорее всего конкатенация строк, либо в виде просто
-сложения строк, либо добавления строки к строке. И именно она легко может вызывать как неоптимальную производительность при неграмотном
-использовании, так и оверхед по памяти, даже при грамотном использовании.
+### String concatenation
+Next, after initializing a string, the most frequent mutable operation with them is most likely string concatenation, either in the form of simply
+adding strings, or adding a string to a string. And it is she who can easily cause both suboptimal performance with illiterate
+use, and memory overhead, even with competent use.

-К сожалению, пока ни один компилятор не оптимизирует первый простой код до уровня второго более оптимального кода, а писать

-Да и в этом случае вполне может возникнуть оверхед по памяти — операции добавления строки обычно во всех реализациях увеличивают

-Поэтому если строку не планируется более модифицировать, но время её жизни ещё не подошло к концу (например, это поле

+Unfortunately, so far no compiler optimizes the first simple code to the level of the second more optimal code, and writing
+such code every time by hand is quite inconvenient. That is, again you have to pay for what you don’t use.
+And in this case, memory overhead may well occur – string addition operations usually increase
+the size of the string buffer in all implementations by at least two times, assuming that something may soon be added to the string again.
+Therefore, if the string is no longer planned to be modified, but its lifetime has not yet come to an end (for example, this is a field
+of some class), you should not forget to do `shrink_to_fit` on it.
 
-Между тем, часто основной сценарий использования строк — это как раз некая подготовка строки путём нескольких модификаций и конкатенаций,
-а затем она где-то хранится, более не меняясь. При этом программист обычно знает, примерно какой размер строк ожидается в этом месте,
-и мог бы выделить буфер для этих промежуточных модификаций прямо на стеке, прибегая к динамической аллокации только при превышении
-размера этого буфера. Однако с текущей реализацией строк это сделать довольно проблематично, либо неудобно.
+Meanwhile, often the main scenario for using strings is just some preparation of the string by several modifications and concatenations,
+and then it is stored somewhere, no longer changing. In this case, the programmer usually knows approximately what size of strings is expected in this place,
+and could allocate a buffer for these intermediate modifications directly on the stack, resorting to dynamic allocation only when exceeding
+the size of this buffer. However, with the current implementation of strings, this is quite problematic, or inconvenient.
 
-Подытожим, что имеем на данный момент:
+Let's summarize what we have at the moment:
 
-- «Из коробки» в С++ для работы со строками сейчас имеется `std::string`.
--  Строки подразумеваются мутабельными, что приводит к обязательному копированию всех символов строки при инициализации и
-   копировании объектов строк.
-- Соответственно, не имеем возможности быстрого копирования строк, даже если не планируем потом менять копию.
-- Конкатенация нескольких строк — задача, могущая выполнятся неоптимально, приводить к оверхеду по памяти, написать оптимальный код сложно.
-- Есть костыль для иммутабельных строк в виде `std::string_view`, однако он не решает вопросы владения строкой, поэтому по сути
-  годится только как тип для передачи параметров в функции, не меняющие строки, с оговоркой, что не может использоваться в функциях,
-  вызывающих C-API, так как не даёт гарантий нуль-терминированности.
-- Ну и к `std::string` есть вопросы, что несмотря на то, что это класс для строк, собственно для работы со строками в нём крайне куцый
-  функционал по сравнению с тем, к чему привыкли в других языках — к примеру нет замены подстрок по шаблону (в других языках это обычно
-  replace, но в С++ эта функция делает совершенно другое), trim, split, join, upper, lower и т. п.
-  Эти функции приходится каждый раз писать самому, и не факт, что у всех это получится оптимально.
+- "Out of the box" in C++ for working with strings there is now `std::string`.
+- Strings are assumed to be mutable, which leads to mandatory copying of all characters of the string during initialization and
+   copying of string objects.
+- Accordingly, we do not have the ability to quickly copy strings, even if we do not plan to change the copy later.
+- Concatenating several strings is a task that can be performed suboptimally, lead to memory overhead, and it is difficult to write optimal code.
+- There is a crutch for immutable strings in the form of `std::string_view`, but it does not solve the issues of string ownership, so in fact
+  it is only suitable as a type for passing parameters to functions that do not change strings, with the caveat that it cannot be used in functions
+  calling C-API, since it does not guarantee null-termination.
+- Well, and there are questions to `std::string` that despite the fact that this is a class for strings, in fact, for working with strings it has an extremely meager
+  functionality compared to what they are used to in other languages – for example, there is no replacement of substrings by a pattern (in other languages this is usually
+  replace, but in C++ this function does something completely different), trim, split, join, upper, lower, etc.
+  These functions have to be written by yourself every time, and it is not a fact that everyone will be able to do this optimally.
 
-Надеюсь, после этого небольшого вступления вам будет более понятно, какие проблемы я решал своей строковой библиотекой и каким образом.
+I hope that after this small introduction you will better understand what problems I solved with my string library and how.
 
-## Библиотека simstr
-Собственно, нельзя сказать, что «я свелосипедил свою реализацию класса для строк».
-Как я ранее показал, сложно, а то и даже невозможно написать один единый строковый класс, хорошо подходящий для всех сценариев
-использования. Именно поэтому у меня не строковый класс, а строковая библиотека, которая содержит несколько разных строковых типов,
-от более простых к более сложным, каждый из которых имеет свои сильные и слабые стороны, и пользователю нужно грамотно подходить к
-вопросу, какой из этих классов в каком случае стоит использовать.
+## Simstr library
+Actually, you can't say that "I reinvented my implementation of the class for strings."
+As I showed earlier, it is difficult, or even impossible, to write one single string class that is well suited for all scenarios
+of use. That is why I don’t have a string class, but a string library, which contains several different string types,
+from simpler to more complex, each of which has its own strengths and weaknesses, and the user needs to competently approach the
+question of which of these classes should be used in which case.
 
-Саму библиотеку я начал потихоньку разрабатывать ещё в 2011-2012 годах, когда у нас уже появилась семантика перемещения, но ещё
-не было std::string_view. Однако сейчас минимальная версия стандарта для работы библиотеки: **C++20** – используются концепты и \<format\>.
+I started developing the library itself little by little back in 2011-2012, when we already had move semantics, but not yet
+there was std::string_view. However, now the minimum standard version for the library to work is: **C++20** – concepts and \<format\> are used.
 
-Сначала я расскажу о классах библиотеки для самих строк, а потом о том, как в ней оптимально решается задача конкатенации строк.
+First, I will talk about the library classes for the strings themselves, and then about how the string concatenation problem is optimally solved in it.
 
-Несколько общих моментов:
-- Все классы для работы со строками шаблонизированы типом символов, но подразумевается, что символы могут быть char, char16_t,
-  char32_t, wchar_t.
-- Все строки имеют явную длину.
-- Классы владельцы строк хранят их с завершающим нулем в конце, который не входит в длину строки.
-- В самой строке могут содержаться нулевые символы, все алгоритмы работают только через длину строки, не обращая на них внимания.
-- Классы владельцы строк могут инициализироваться строками другого типа символов, выполняя конвертацию между UTF-8, UTF-16, UTF-32.
-- Для смены регистра символов и сравнения строк без учёта регистра используются встроенные таблицы для первой плоскости юникода
-  (до 0xFFFF). Строки считаются представленными в кодировке UTF-8, UTF-16, UTF-32 соответственно.
-  Однако не делается нормализация строк и не обрабатываются ситуации, когда смена регистра символа приводит к изменению их количества.
-  То есть преобразование регистра символов соответствует `std::towupper`, `std::towlower` для unicode локали,
-  только быстрее и может работать с любым видом символов.
-  Если вам нужна строгая работа с юникодом, используйте другие средства, например ICU.
+Several general points:
+- All classes for working with strings are templated by the type of characters, but it is assumed that the characters can be `char`, `char8_t`, `char16_t`,
+  `char32_t`, `wchar_t`.
+- All strings have an explicit length.
+- The string owner classes store them with a trailing zero at the end, which is not included in the length of the string.
+- The string itself can contain zero characters, all algorithms work only through the length of the string, without paying attention to them.
+- The library considers different string types to be "compatible" if they have the same character size.
+  That is, `char` and `char8_t` are always identical, and also in Linux `wchar_t` and `char32_t` are identical, and in Windows `wchar_t` and `char16_t`.
+- The string owner classes can be initialized with strings of another character type, performing conversion between UTF-8, UTF-16, UTF-32.
+  Moreover, if the strings are of different but compatible types, they are simply copied without conversion.
+- Built-in tables for the first plane of Unicode are used to change the case of characters and compare strings case-insensitively
+  (up to 0xFFFF). Strings are considered to be represented in UTF-8, UTF-16, UTF-32 encoding, respectively.
+  However, string normalization is not done and situations where changing the case of a character leads to a change in their number are not handled.
+  That is, the case conversion of characters corresponds to `std::towupper`, `std::towlower` for the unicode locale,
+  only faster and can work with any type of characters.
+  If you need strict work with unicode, use other tools, such as ICU.
 
-### Классы строк.
+### String classes.
 
-#### Первый самый простой класс строки называется, естественно, `simple_str` :)
+#### The first simplest string class is called, of course, `simple_str` :)
 (simstr::simple_str)
 
-Класс просто представляет собой указатель на начало константной строки и её длину, по сути то же самое, что `std::string_view`.
-Предназначен для работы с иммутабельными строками, не владеющий ими, то есть вы должны сами озаботиться тем, что реальная строка,
-представленная через `simple_str` – жива во время его использования.
+The class simply represents a pointer to the beginning of a constant string and its length, in fact the same as `std::string_view`.
+It is intended for working with immutable strings, not owning them, that is, you must take care that the real string,
+represented through `simple_str` – is alive during its use.
 
-Реализует все строковые методы, не модифицирующие строку.
+Implements all string methods that do not modify the string.
 
-Алиасы:
-- `ssa` для simple_str\<char\>
-- `ssu` для simple_str\<char16_t\>
-- `ssw` для simple_str\<wchar_t>
-- `ssuu` для simple_str\<char32_t\>
+Aliases:
+- `ssa` for simple_str\<char\>
+- `ssb` for simple_str\<char8_t\>
+- `ssu` for simple_str\<char16_t\>
+- `ssw` for simple_str\<wchar_t>
+- `ssuu` for simple_str\<char32_t\>
 
-Применяется в основном для передачи строк как параметр функций, не модифицирующих переданную строку, вместо `const std::string&`,
-а также для локальных переменных при работе с частями строк.
+It is used mainly for passing strings as a parameter to functions that do not modify the passed string, instead of `const std::string&`,
+as well as for local variables when working with parts of strings.
 
-#### Второй класс — `simple_str_nt`
+#### The second class is `simple_str_nt`
 (simstr::simple_str_nt)
 
-По устройству и назначению совпадает с `simple_str`, но дает гарантии нуль-терминированности строки.
-То есть если функции надо переданный параметр без изменений передать дальше как C-строку в какое то API, она должна использовать для
-параметра тип `simple_str_nt`.
-Все классы владеющих строк (simstr::sstring, simstr::lstring) могут быть преобразованы в `simple_str_nt`, так как хранят строки с завершающим нулём.
-Это позволяет писать функции с единым типом параметра, принимающим на вход любой тип владеющих строковых объектов.
+In terms of structure and purpose, it coincides with `simple_str`, but guarantees null-termination of the string.
+That is, if the function needs to pass the passed parameter further as a C-string to some API without changes, it should use the
+`simple_str_nt` type for the parameter.
+All classes of owning strings (simstr::sstring, simstr::lstring) can be converted to `simple_str_nt`, since they store strings with a trailing zero.
+This allows you to write functions with a single parameter type that accepts any type of owning string objects as input.
 
-Алиасы:
-- `stra` для simple_str_nt\<char>
-- `stru` для simple_str_nt\<char16_t>
-- `strw` для simple_str_nt\<wchar_t>
-- `struu` для simple_str_nt\<char32_t>
+Aliases:
+- `stra` for simple_str_nt\<char>
+- `strb` for simple_str_nt\<char8_t>
+- `stru` for simple_str_nt\<char16_t>
+- `strw` for simple_str_nt\<wchar_t>
+- `struu` for simple_str_nt\<char32_t>
 
-Может инициализироваться строковыми литералами:
+Can be initialized with string literals:
 ```cpp
     stra text = "Text";
 ```
-Длина в этом случае вычисляется сразу при компиляции. Аналогично `simple_str_nt` создается с помощью `operator""_ss`:
+In this case, the length is calculated immediately at compile time. Similarly, `simple_str_nt` is created using `operator""_ss`:
 
 ```cpp
     stringa result = "Count: "_ss + count;
 ```
 
-#### Класс sstring (shared string).
+#### Sstring class (shared string).
 (simstr::sstring)
 
-Класс, умеющий хранить иммутабельную строку.
-То есть ему можно присвоить некую строку только целиком, модифицировать символы строки нельзя.
+A class that can store an immutable string.
+That is, you can only assign a string to it entirely, you cannot modify the characters of the string.
 
-Владеет строкой, управляет памятью для символов строки.
-Хранит со строками завершающий нуль, и может быть источником для `simple_str_nt`, для передачи в C-API.
-Так же, как и `simple_str`, реализует все методы, не модифицирующие строку.
+Owns the string, manages the memory for the characters of the string.
+Stores a trailing zero with the strings, and can be a source for `simple_str_nt`, for passing to C-API.
+Like `simple_str`, it implements all methods that do not modify the string.
 
-Алиасы:
-- `stringa` для sstring\<char>
-- `stringu` для sstring\<char16_t>
-- `stringw` для sstring\<wchar_t>
-- `stringuu` для sstring\<char32_t>
+Aliases:
+- `stringa` for sstring\<char>
+- `stringb` for sstring\<char8_t>
+- `stringu` for sstring\<char16_t>
+- `stringw` for sstring\<wchar_t>
+- `stringuu` for sstring\<char32_t>
 
 
-То, что хранимая строка иммутабельна, позволяет применить ряд оптимизаций:
-- Для строк, не подходящих для SSO,  использует общий разделяемый буфер с атомарным счётчиком ссылок.
-  Позволяет быстро копировать строку без необходимости блокировок доступа к содержимому буфера.
-- Нет необходимости хранить размер буфера (capacity) — всё равно мы ничего не дописываем в буфер.
-- Позволяет просто ссылаться на литералы программы, не копируя их символы в какой-либо буфер:
+The fact that the stored string is immutable allows you to apply a number of optimizations:
+- For strings that are not suitable for SSO, it uses a common shared buffer with an atomic reference counter.
+  Allows you to quickly copy a string without the need to block access to the contents of the buffer.
+- There is no need to store the buffer size (capacity) – we are not adding anything to the buffer anyway.
+- Allows you to simply refer to program literals without copying their characters to any buffer:
     ```cpp
-	stringa str = "Hello!";       // Ничего не стоит, не копирует байты строки
-	stringa ltr = stra{"Hello!"}; // А вот тут копирует байты строки в ltr
+	stringa str = "Hello!";       // Costs nothing, does not copy the bytes of the string
+	stringa ltr = stra{"Hello!"}; // But here it copies the bytes of the string to ltr
     ```

+#### Class lstring<K, N, forShared> (local string)
 (simstr::lstring)
 
-Класс, хранящий строку и позволяющий её модифицировать.
-Владеет строкой, управляет памятью для символов строки.
-Хранит со строками завершающий нуль, и может быть источником для `simple_str_nt`, для передачи в C-API.
-Как и все остальные классы, реализует все методы, не модифицирующие строку.
+A class that stores a string and allows it to be modified.
+Owns the string, manages the memory for the characters of the string.
+Stores a trailing zero with the strings, and can be a source for `simple_str_nt`, for passing to C-API.
+Like all other classes, it implements all methods that do not modify the string.
 
-В качестве `N` в параметре шаблона задаётся размер внутреннего буфера для хранения символов.
-Строки длиной до N символов хранятся внутри объекта, а при превышении этого количества — аллоцируется динамический буфер,
-в который сохраняются символы. При копировании объекта все символы также всегда копируются.
+The size of the internal buffer for storing characters is specified as `N` in the template parameter.
+Strings up to N characters long are stored inside the object, and when this number is exceeded, a dynamic buffer is allocated,
+in which the characters are saved. When copying an object, all characters are also always copied.
 
-Если `forShare` == true и символы не помещаются в локальный буфер, то динамический буфер создается с дополнительным местом,
-так чтобы совпадать по структуре с буфером `sstring`. Тогда при перемещении `lstring` в `sstring` – переместится только указатель
-на буфер, без излишнего копирования символов.
+If `forShare` == true and the characters do not fit into the local buffer, then a dynamic buffer is created with additional space,
+so that it matches the structure of the `sstring` buffer. Then, when moving `lstring` to `sstring` – only the pointer will move
+to the buffer, without unnecessary copying of characters.
 
-Этот класс удобен для работы со строками как локальная переменная на стеке.
-Обычно мы предполагаем примерный размер строк, с котороми будем работать, и можем создать локальную строку с буфером на стеке,
-и работать с ней. При этом не опасаясь переполнения буфера, так как в этом случае строка переключится на динамический буфер.
+This class is convenient for working with strings as a local variable on the stack.
+Usually we assume the approximate size of the strings we will be working with, and we can create a local string with a buffer on the stack,
+and work with it. At the same time, without fear of buffer overflow, since in this case the string will switch to a dynamic buffer.

-В этом примере вы наверняка заметили, как конкатенируются строки и задались вопросом — как же при двух сложениях считалась
-длина всего результата, чтобы выделить необходимое место сразу за один раз, без промежуточных буферов?
+In this example, you probably noticed how strings are concatenated and wondered – how was the
+length of the entire result calculated with two additions in order to allocate the necessary space at once, without intermediate buffers?
 
-Ответ на этот вопрос:
+The answer to this question:
 
-### Строковые выражения
-Дело в том, что в библиотеке нет сложения строковых объектов как такового. Сложение выполняется для «строковых выражений».
+### String Expressions
+The fact is that there is no addition of string objects as such in the library. Addition is performed for "string expressions".
 
-*Строковое выражение* — это любой объект произвольного типа, имеющий функции `length` и `place`.
-Функция `length` – возвращает длину строки, функция `place` – помещает символы строки в переданный ей буфер.
+A *string expression* is any object of arbitrary type that has `length` and `place` functions.
+The `length` function returns the length of the string, and the `place` function places the characters of the string into the buffer passed to it.
 
-Любая владеющая строка (simstr::sstring, simstr::lstring) может инициализироваться строковым выражением — она запрашивает у него длину,
-выделяет место для хранения символов, и передает это место строковому выражению, вызывая его функцию place.
+Any owning string (simstr::sstring, simstr::lstring) can be initialized with a string expression — it requests its length,
+allocates space for storing characters, and passes this space to the string expression, calling its place function.
 
-Для строковых выражений определена шаблонная функция сложения:
+In addition, all string expressions included in `simstr` can be converted to standard strings (`std::basic_string`)
+compatible character types, which allows you to use fast concatenation where replacing `std::string` is not yet possible.
+Compatible character types are those that match in size.
+To get a standard string before C++23, using `resize`, and then fill it using `data()`, starting with C++23
+the more optimal `resize_and_overwrite` is used.
+
+A template addition function is defined for string expressions:
 ```cpp
     template<StrExpr A, StrExprForType<typename A::symb_type> B>
     inline auto operator + (const A& a, const B& b) {

-`strexprjoin` – шаблонный тип, который сам является строковым выражением.
-В себе он хранит ссылки на два переданных ему строковых выражения.
-При запросе длины он выдает сумму длин двух строковых выражений, а при размещении символов — сначала размещает
-в переданном буфере первое выражение, затем второе.
+`strexprjoin` is a template type that is itself a string expression.
+It stores references to the two string expressions passed to it.
+When the length is requested, it returns the sum of the lengths of the two string expressions, and when placing characters, it first places

-Таким образом, операция сложения строковых выражений создает объект, также являющийся строковым выражением,
-к которому также может быть применена следующая операция сложения, и который рекурсивно хранит ссылки на слагаемые части,
-каждая из которых знает свой размер и умеет размещать себя в буфере результата. И так далее, к каждому получаемому
-строковому выражению можно снова применить `operator +`, формируя цепочку из нескольких строковых выражений,
-и в итоге "материализовать" последний получившийся объект, который сначала посчитает размер всей общей памяти для
-конечного результата, а затем разместит вложенные подвыражения в один буфер.
+Thus, the addition operation of string expressions creates an object that is also a string expression,
+to which the next addition operation can also be applied, and which recursively stores references to the component parts,
+each of which knows its size and knows how to place itself in the result buffer. And so on, to each resulting
+string expression, you can reapply `operator +`, forming a chain of several string expressions,
+and eventually "materialize" the last resulting object, which first calculates the size of the entire total memory for
+the final result, and then places the nested subexpressions into one buffer.
 
-Все строковые типы библиотеки сами являются строковыми выражениями, то есть могут служить слагаемыми в конкатенациях
-строковых выражений.
+The addition operation of string expressions allows you to concatenate string expressions of different but compatible types.
+That is, in one expression you can mix `""` and `u8""`, in Linux `L""` and `U""`, in Windows `L""` and `u""`
+character types. There are examples in `tests\test_str.cpp TEST(SimStr, StrPrintfU8)`.
 
-Также `operator+` определён для строковых выражений и строковых литералов, строковых выражений и чисел (числа конвертируются
-в десятичное представление), а также вы можете сами добавить желаемые типы.
+All string types in the library are themselves string expressions, that is, they can serve as terms in concatenations
+of string expressions.
 
-Пример:
+Also, `operator+` is defined for string expressions and string literals, string expressions and numbers (numbers are converted
+to decimal representation), and you can add the desired types yourself.
+
+Example:
 ```cpp
 	stringa text = header + " count=" + count + ", done";
 ```
 
-Существует несколько типов строковых выражений "из коробки", для выполнения различных операций со строками:
+For standard strings (`std::basic_string` and `std::basic_string_view`) addition operators with strings have also been made
+expressions, so variables of these types also directly participate in concatenation operations.
+However, standard strings can only participate directly in string expressions when
+the other operand is also a string expression. If the other operand is not a string expression,
+use a unary `operator+` before standard strings to turn `std::basic_string` or `std::basic_string_view`
+to a string expression.
 
-#### expr_spaces<ТипСимвола, КоличествоСимволов, Символ = ' '>{}
-Выдает строку длиной КоличествоСимволов,  заполненную заданным символом. Количество символов и символ - константы времени
-компиляции. Для некоторых случаев есть сокращенная запись:
+Example:
+```cpp
+std::string make_text(const std::string& text, std::string_view what, int count) {
+    //     + turns text into a string expression, and then they are added together
+    return +text + " " + count + " " + what + e_if(count > 1, "s");
+    //                                 what participates directly as an operand with a string expression
+}
+std::string make_answer(const std::string& text, std::string_view what, int count) {
+    return "Answer is: " + +text + " " + count + " " + what + e_if(count > 1, "s");
+    //                     + turns text into a string expression, and it can be added to the previous string literal
+}
+```
+That is, the unary `+` is only needed somewhere at the beginning of the expression if the other operand is not a string expression.
 
-    e_spca(КоличествоСимволов) - строка char пробелов
-    e_spcw(КоличествоСимволов) - строка w_char пробелов
+There are several types of string expressions "out of the box" for performing various operations on strings:
 
-#### expr_pad<ТипСимвола>{КоличествоСимволов, Символ = ' '}
-Выдает строку длиной КоличествоСимволов, заполненную заданным символом.
-Количество символов и символ могут задаваться в рантайме. Сокращенная запись:
+#### expr_spaces<CharacterType, NumberOfCharacters, Symbol = ' '>{}
+Returns a string of length NumberOfCharacters, filled with the specified character. The number of characters and the symbol are compile-time constants. For some cases, there is a shorthand notation:
 
-    e_c(КоличествоСимволов, Символ)
+    e_spca(NumberOfCharacters) - string of char spaces
+    e_spcw(NumberOfCharacters) - string of w_char spaces
+
+#### expr_pad<CharacterType>{NumberOfCharacters, Symbol = ' '}
+Returns a string of length NumberOfCharacters, filled with the specified character.
+The number of characters and the symbol can be specified at runtime. Shorthand notation:
+
+    e_c(NumberOfCharacters, Symbol)
+
+#### e_repeat{Str, count}
+Generates a repetition of a string literal or expression `Str` `count` times.
+
+    e_repeat("aa", 10);
 
 #### e_choice(bool Condition, StrExpr1, StrExpr2)
-Если Condition == true, результат будет равен StrExpr1, иначе StrExpr2.
+If Condition == true, the result will be StrExpr1, otherwise StrExpr2.
 
 #### e_if(bool Condition, StrExpr1)
-Если Condition == true, результат будет равен StrExpr1, иначе пустая строка.
+If Condition == true, the result will be StrExpr1, otherwise an empty string.
 
-#### expr_num<ТипСимвола>(ЦелоеЧисло)
-Конвертирует число в десятичное представление. Редко используется, так как для строковых выражений и чисел
-переопределен оператор "+", и число можно просто написать как `text + number`;
+#### expr_num<CharacterType>(Integer)
+Converts a number to decimal representation. Rarely used, since the "+" operator is overloaded for string expressions and numbers, and the number can simply be written as `text + number`;
 
-#### expr_real<ТипСимвола>(ВещественноеЧисло)
-конвертирует число в десятичное представление. Редко используется, так как для строковых выражений и чисел
-переопределен оператор "+", и число можно просто написать как `text + number`;
+#### expr_real<CharacterType>(RealNumber)
+converts a number to decimal representation. Rarely used, since the "+" operator is overloaded for string expressions and numbers, and the number can simply be written as `text + number`;
 
-#### e_join<bool ПослеПоследнего = false, bool ТолькоНеПустые = false>(контейнер, "Разделитель")
-Конкатенирует все строки в контейнере, используя разделитель. Если ПослеПоследнего == true,
-то разделитель добавляется и после последнего элемента контейнера, иначе только между элементами.
-Если ТолькоНеПустые == true, то пустые строки пропускаются без добавления разделителя.
+#### e_join<bool AfterLast = false, bool OnlyNotEmpty = false>(container, "Separator")
+Concatenates all strings in the container, using a separator. If AfterLast == true,
+then the separator is added after the last element of the container as well, otherwise only between elements.
+If OnlyNotEmpty == true, then empty strings are skipped without adding a separator.
 
-#### e_repl(ИсходнаяСтрока, "Искать", "Заменять")
-Заменяет в исходной строке вхождения "Искать" на "Заменять".
-Шаблоны поиска и замены - строковые литералы времени компиляции.
+#### e_repl(OriginalString, "Search", "Replace")
+Replaces occurrences of "Search" in the original string with "Replace".
+Search and replace patterns are compile-time string literals.
 
-#### expr_replaced<ТипСимвола>{ИсходнаяСтрока, Искать, Заменять}
-Заменяет в исходной строке вхождения Искать на Заменять.
-Шаблоны поиска и замены - могут быть любыми строковыми объектами в рантайме.
+#### expr_replaced<CharacterType>{OriginalString, Search, Replace}
+Replaces occurrences of Search in the original string with Replace.
+Search and replace patterns can be any string objects at runtime.
 
-#### empty_expr<ТипСимвола>
-Выдает пустую строку. Сокращённая запись — eea, eeu, eew, eeuu. Применяется если формирование строки начинается с числа и строкового литерала:
+#### empty_expr<CharacterType>
+Returns an empty string. Abbreviated notation — eea, eeu, eew, eeuu. Used if the string formation starts with a number and a string literal:
 ```cpp
 	str = eea + count + " times.";
 ```
-так как оператор сложения определён только для сложения строкового выражения и числа.
-Также замечу, что существует `operator""_ss`, который превращает строковый литерал в объект `simple_str_nt`, который уже является строковым выражением:
+since the addition operator is only defined for adding a string expression and a number.
+I also note that there is `operator""_ss`, which turns a string literal into a `simple_str_nt` object, which is already a string expression:
 ```cpp
 	str = "Count = "_ss + count;
     ...
     str = count + " times."_ss;
 ```
 
-#### Свои строковые выражения
-Вы можете сами создавать свои типы строковых выражений для оптимального формирования строк в нужных вам целях и алгоритмах.
-Для этого просто создайте тип с методами `length`, `place` и `typename symb_type`.

-### Класс chunked_string_builder
+### Class chunked_string_builder
 
-Предназначен для конкатенации множества строк.
-Когда вам нужно последовательно формировать длинный текст из множества небольших кусочков (например, формируете html ответ
-и т. п.) - последовательно складывать всё в один строковый объект крайне неоптимально — будет много переаллокаций и
-перекопирования уже накопленных символов. В этом случае удобно использовать chunked_string_builder — всё, что он умеет,
-это прибавлять строку к накопленным символам. Однако делает он это не в единый последовательный буфер памяти, а в отдельные
-буфера, не меньше чем заданное выравнивание. При заполнении очередного буфера он просто создает ещё один буфер и продолжает
-складывать данные в него.
+Designed for concatenating multiple strings.
+When you need to sequentially form a long text from many small pieces (for example, you are forming an html response
+etc.) - sequentially adding everything to one string object is extremely suboptimal - there will be many reallocations and
+copying of already accumulated characters. In this case, it is convenient to use chunked_string_builder - all it can do is
+add a string to the accumulated characters. However, it does this not in a single sequential memory buffer, but in separate
+buffers, no less than the specified alignment. When filling the next buffer, it simply creates another buffer and continues
+to add data to it.
 
-То есть допустим вы задали выравнивание 1024.
-Добавили несколько строк, заполнили буфер  на 100 символов. И добавляете строку длинной 3000 символов.
-При этом 924 символа скопируются в первый буфер, заполнив его до конца.
-Для оставшихся 2076 создастся буфер размером 3072 символа, и они скопируются в него, в нём останется место для 996 символов.
-Так последовательно каждый буфер заполняется до конца, и имеет размер кратный заданному выравниванию.
-Таким образом избегаются переаллокации и перекопирование обработанных символов.
+That is, suppose you set the alignment to 1024.
+Added several strings, filled the buffer with 100 characters. And you add a string of 3000 characters long.
+In this case, 924 characters will be copied to the first buffer, filling it to the end.
+For the remaining 2076, a buffer of 3072 characters will be created, and they will be copied into it, leaving space for 996 characters in it.
+Thus, each buffer is sequentially filled to the end and has a size that is a multiple of the specified alignment.
+This avoids reallocations and copying of processed characters.
 
-После окончательного заполнения вы можете работать с накопленными данными — либо слить все буфера в одну последовательную
-строку (размер для буфера которой вы теперь уже знаете), либо перебирать их по отдельности, например, посылая эти буфера
-в сеть. Либо последовательно копируя данные в буфер заданного размера.
+After the final filling, you can work with the accumulated data - either merge all the buffers into one sequential
+string (the size for the buffer of which you now already know), or iterate over them separately, for example, sending these buffers
+to the network. Or sequentially copying data into a buffer of a given size.

+# Строки в С++
+(, что с вами не так?)

+
+<cite>
+В ретроспективе 1991 года по истории C++ его создатель Бьярне Страуструп назвал отсутствие стандартного строкового типа
+(и некоторых других стандартных типов) в C++ 1.0 худшей ошибкой, которую он допустил при его разработке:
+"the absence of those led to everybody re-inventing the wheel and to an unnecessary diversity in the most fundamental classes"
+(«Их отсутствие привело к тому, что все заново изобретали велосипед, и к ненужному разнообразию в самых фундаментальных классах»).
+</cite>
+
+## Что было и есть
+Во вступительной части я хочу немного описать, каково ныне состояние со строками в С++, как мы к нему докатились и почему оно таково.
+А также описать недостатки текущих реализаций, чтобы были понятны решения, которые я использую в своей библиотеке строк.
+
+Собственно, изначально как такового стандартного типа для строк в С++ не было.
+Для работы со строками использовался подход из C – строка есть указатель на массив байтов, оканчивающихся нулём.
+Недостатки таких строк — невозможно в строке использовать байт `0`, т. е. не подходит для бинарных данных,
+непонятна стратегия управления/владения ресурсами, ну и основной недостаток — длину строки приходится вычислять каждый раз,
+перебирая все её символы.
+
+Откуда ноги растут у такого решения вполне понятно — со времён динозавров: как динозавры были большие, с маленьким мозгом и
+короткими ручками, так и компьютеры были большие, память у них была маленькая, а строки короткими. Сэкономить память на хранении длины строки было важнее, чем потерять время на повторный подсчет длины.
+
+Первые попытки стандартизировать строки как класс начались только в С++98 - std::string появился, как часть STL, и как
+многое из STL, крайне неоднозначно воспринимался программистами.
+
+И первое, что приходит в голову при улучшении C-строк — надо хранить длину строки:
+```cpp
+    struct simple_string {
+        const char* data;
+        size_t length;
+    };
+```
+
+При наличии такой строки, уже множество алгоритмов значительно оптимизируются.
+Например, при сравнении двух строк на равенство мы можем даже не начинать сравнивать их символы, если длины строк не равны.
+Более того, этих данных абсолютно достаточно для всех методов, которые не модифицируют строку.
+Также заметим, что такой объект на современных 64-битных архитектурах прекрасно передается в функции по значению —
+оба его поля укладываются в регистры (ну, кроме windows), что облегчает работу оптимизатору компилятора.
+
+Между тем, такое решение попало в стандарт только аж в С++17, в виде `std::string_view`.
+Видимо, только тогда до комитета смогли донести мысль, что строки строкам рознь, и использовать только один универсальный объект
+для строк — по меньшей мере может приводить к уменьшению производительности, а также нарушает принцип «не плати за то,
+чем не пользуешься». Почему же «строки строкам рознь» и почему нам мало одного типа для строки, рассмотрим как раз далее.
+
+### Ресурсы
+И следующий вопрос, возникающий со строками — это владение ресурсами.
+Практически каждый крупный фреймворк решал эту задачу самостоятельно, изобретая свои велосипеды.
+У нас есть `std::string`, в QT у нас `QString`, в MFC - `CString`, в ATL - `CAtlString`, свои строки есть в Folly,
+в общем, “тысячи их”, любой игровой движок начинают с того, чтобы написать свои строки.
+
+Многие из этих реализаций в аспекте управления ресурсами для улучшения производительности использовали подход
+**COW** – “Copy On Write”. При этом объект строки ссылался на некий разделяемый между несколькими объектами буфер с символами
+строки и счётчиком ссылок на этот буфер, что позволяло быстро создавать копию строки, а реально копировать символы только
+при её модификации.
+
+Но все они совпадали в одном — строка всегда предполагалась мутабельной, то есть что мы можем модифицировать символы в буфере строки.
+
+### Мутабельность / иммутабельность
+Из-за этого подход **COW** умер к С++11: при каждой операции, могущей модифицировать символы строки приходилось проверять,
+не ссылаемся ли мы на разделяемый буфер и если да, то копировать символы в другой буфер.
+В многопоточной же среде потом ещё и проверять, не надо ли теперь освобождать старый буфер, и естественно всё это обмазавшись
+локами или атомиками, что тоже не бесплатно.
+Поэтому, начиная с С++11 `std::string` не использует **COW**, и каждое копирование объекта строки приводит и к копированию
+всех символов строки в другой буфер.
+
+Естественно, что каждый новый буфер требует аллокации памяти, что пытаются немного оптимизировать за счёт **SSO** –
+“Small String Optimization”, когда объект строки содержит внутри себя небольшой буфер и символы коротких строк
+располагаются прямо в нём.
+Но это уже зависит от реализации:  в одних библиотеках помещают в объект строки до 15 байт, в некоторых до 23.
+Однако эта оптимизация тоже палка о двух концах, и может в различных реализациях усложнить перемещение строки - если она хранит
+указатель на свой внутренний буфер, его придётся корректировать.
+
+А без COW мутабельность строк приводит к тому, что любая инициализация объекта строки приводит к копированию байтов.
+Посмотрим такой код:
+```cpp
+    const char* text1 = "Hello, World";         // ничего не стоит
+    std::string_view text2 = "Hello, World";    // Ничего не стоит, вычисляет длину строки при компиляции
+    std::string text3 = "Hello, World";         // В рантайме каждый раз копирует символы строки
+```
+
+(Удостоверится в правдивости комментариев можно на https://godbolt.org/z/51oKGWT5T )
+
+Но если нам дальше по коду не нужно никак модифицировать строку, мы зря платим за аллокацию, копирование символов,
+а также за деструктор строки. То есть хотелось бы иметь как минимум два варианта строк — мутабельные и иммутабельные,
+чтобы явно дать понять компилятору, что мы не собираемся модифицировать строку.
+Или банальный пример — мы парсим какой-то входящий буфер данных, нам нужно проверить, равен ли некий кусок буфера строке
+”hello” на «чистом С++», т. е. без всяких memcmp и strcmp. До появления string_view приходилось делать примерно так:
+```cpp
+    bool is_part_buffer_equal_hello(const char* data, int start, int end) {
+        return std::string(data + start, end - start) == "hello";
+    }
+```
+Тут получается, сначала копируются символы из буфера data в буфер временной строки, возможно с аллокацией памяти, и лишь
+потом временная строка сравнивается с ”hello”, а потом ещё и деструктор и раскрутка стека на случай исключения.
+
+При использовании же вместо `std::string` `std::string_view` – код на C++ почти не меняется:
+```cpp
+    bool is_part_buffer_equal_hello_view(const char* data, int start, int end) {
+        return std::string_view(data + start, end - start) == "hello";
+    }
+```
+Однако генерируемый машинный код значительно преобразуется, достигая уровня ручного С-кода — там просто сравнивается,
+что end – start == 5 и дальше кусок начального буфера сравнивается через memcmp со строкой ”hello”
+(при -O2 c константами 1819043176 (’hell’) и 111 (’o’)).
+Ни создания временного объекта, ни копирования байтов, ни деструктора, ни раскрутки стека для исключений.
+Убедится можно на https://godbolt.org/z/9fo188e7c
+
+Казалось бы, ну вот же в С++17 появился `string_view`, пожалуйста, используй его в параметрах своих функций вместо `const std::string&`,
+и будет счастье. Но тут тоже есть нюанс — всё отлично работает, пока нам не нужно передать строку в стороннее C-API: string_view не даёт
+гарантий нуль-терминированности строки, поэтому его data() нельзя передать в стороннее C-API, и потому всё-равно придётся сначала
+скопировать его в `std::string`. А раз нужен `std::string`, то и параметром функции оптимальнее cделать `const std::string&`
+и далее по цепочке, все параметры вновь станут `const std::string&`.
+
+### Конкатенация строк
+Далее, после инициализации строки, самая частая мутабельная операция с ними, скорее всего конкатенация строк, либо в виде просто
+сложения строк, либо добавления строки к строке. И именно она легко может вызывать как неоптимальную производительность при неграмотном
+использовании, так и оверхед по памяти, даже при грамотном использовании.
+
+Рассмотрим простой код ( https://godbolt.org/z/odx7W1Pv7 )
+```cpp
+    #include <string>
+    void some_outer_function(const std::string&);
+
+    void func(const std::string& s1, const std::string& s2) {
+        std::string concat = s1 + s2 + "hello";
+        some_outer_function(concat);
+    }
+```
+Как видим, и в clang, и в GCC создается несколько временных объектов, в которые последовательно перекладываются символы строк,
+и как результат — мы получаем несколько лишних аллокаций для промежуточных буферов, символы из строк копируются несколько лишних
+раз из промежуточных буферов. В идеале для лучшей производительности такой код нужно переписать так:
+```cpp
+    #include <string>
+    void some_outer_function(const std::string&);
+
+    void func(const std::string& s1, const std::string& s2) {
+        static const std::string_view hello = "hello";
+        std::string concat;
+        concat.reserve(s1.size() + s2.size() + hello.size());
+        concat += s1;
+        concat += s2;
+        concat += hello;
+        some_outer_function(concat);
+    }
+```
+
+К сожалению, пока ни один компилятор не оптимизирует первый простой код до уровня второго более оптимального кода, а писать
+такой код каждый раз руками довольно неудобно. То есть опять приходится платить за то, чем не пользуешься.
+Да и в этом случае вполне может возникнуть оверхед по памяти — операции добавления строки обычно во всех реализациях увеличивают
+размер буфера строки не меньше, чем в два раза, считая, что скоро к строке могут снова что-нибудь добавить.
+Поэтому если строку не планируется более модифицировать, но время её жизни ещё не подошло к концу (например, это поле
+какого-либо класса), нужно ещё не забыть сделать на ней `shrink_to_fit`.
+
+Между тем, часто основной сценарий использования строк — это как раз некая подготовка строки путём нескольких модификаций и конкатенаций,
+а затем она где-то хранится, более не меняясь. При этом программист обычно знает, примерно какой размер строк ожидается в этом месте,
+и мог бы выделить буфер для этих промежуточных модификаций прямо на стеке, прибегая к динамической аллокации только при превышении
+размера этого буфера. Однако с текущей реализацией строк это сделать довольно проблематично, либо неудобно.
+
+Подытожим, что имеем на данный момент:
+
+- «Из коробки» в С++ для работы со строками сейчас имеется `std::string`.
+-  Строки подразумеваются мутабельными, что приводит к обязательному копированию всех символов строки при инициализации и
+   копировании объектов строк.
+- Соответственно, не имеем возможности быстрого копирования строк, даже если не планируем потом менять копию.
+- Конкатенация нескольких строк — задача, могущая выполнятся неоптимально, приводить к оверхеду по памяти, написать оптимальный код сложно.
+- Есть костыль для иммутабельных строк в виде `std::string_view`, однако он не решает вопросы владения строкой, поэтому по сути
+  годится только как тип для передачи параметров в функции, не меняющие строки, с оговоркой, что не может использоваться в функциях,
+  вызывающих C-API, так как не даёт гарантий нуль-терминированности.
+- Ну и к `std::string` есть вопросы, что несмотря на то, что это класс для строк, собственно для работы со строками в нём крайне куцый
+  функционал по сравнению с тем, к чему привыкли в других языках — к примеру нет замены подстрок по шаблону (в других языках это обычно
+  replace, но в С++ эта функция делает совершенно другое), trim, split, join, upper, lower и т. п.
+  Эти функции приходится каждый раз писать самому, и не факт, что у всех это получится оптимально.
+
+Надеюсь, после этого небольшого вступления вам будет более понятно, какие проблемы я решал своей строковой библиотекой и каким образом.
+
+## Библиотека simstr
+Собственно, нельзя сказать, что «я свелосипедил свою реализацию класса для строк».
+Как я ранее показал, сложно, а то и даже невозможно написать один единый строковый класс, хорошо подходящий для всех сценариев
+использования. Именно поэтому у меня не строковый класс, а строковая библиотека, которая содержит несколько разных строковых типов,
+от более простых к более сложным, каждый из которых имеет свои сильные и слабые стороны, и пользователю нужно грамотно подходить к
+вопросу, какой из этих классов в каком случае стоит использовать.
+
+Саму библиотеку я начал потихоньку разрабатывать ещё в 2011-2012 годах, когда у нас уже появилась семантика перемещения, но ещё
+не было std::string_view. Однако сейчас минимальная версия стандарта для работы библиотеки: **C++20** – используются концепты и \<format\>.
+
+Сначала я расскажу о классах библиотеки для самих строк, а потом о том, как в ней оптимально решается задача конкатенации строк.
+
+Несколько общих моментов:
+- Все классы для работы со строками шаблонизированы типом символов, но подразумевается, что символы могут быть `char`, `char8_t`, `char16_t`,
+  `char32_t`, `wchar_t`.
+- Все строки имеют явную длину.
+- Классы владельцы строк хранят их с завершающим нулем в конце, который не входит в длину строки.
+- В самой строке могут содержаться нулевые символы, все алгоритмы работают только через длину строки, не обращая на них внимания.
+- Библиотека считает разные строковые типы "совместимыми", если они имеют одинаковый размер символов.
+  То есть `char` и `char8_t` всегда тождественны, а также в Linux тождественны `wchar_t` и `char32_t`, а в Windows `wchar_t` и `char16_t`.
+- Классы владельцы строк могут инициализироваться строками другого типа символов, выполняя конвертацию между UTF-8, UTF-16, UTF-32.
+  При этом если строки разных, но совместимых типов, они просто копируются без конвертации.
+- Для смены регистра символов и сравнения строк без учёта регистра используются встроенные таблицы для первой плоскости юникода
+  (до 0xFFFF). Строки считаются представленными в кодировке UTF-8, UTF-16, UTF-32 соответственно.
+  Однако не делается нормализация строк и не обрабатываются ситуации, когда смена регистра символа приводит к изменению их количества.
+  То есть преобразование регистра символов соответствует `std::towupper`, `std::towlower` для unicode локали,
+  только быстрее и может работать с любым видом символов.
+  Если вам нужна строгая работа с юникодом, используйте другие средства, например ICU.
+
+### Классы строк.
+
+#### Первый самый простой класс строки называется, естественно, `simple_str` :)
+(simstr::simple_str)
+
+Класс просто представляет собой указатель на начало константной строки и её длину, по сути то же самое, что `std::string_view`.
+Предназначен для работы с иммутабельными строками, не владеющий ими, то есть вы должны сами озаботиться тем, что реальная строка,
+представленная через `simple_str` – жива во время его использования.
+
+Реализует все строковые методы, не модифицирующие строку.
+
+Алиасы:
+- `ssa` для simple_str\<char\>
+- `ssb` для simple_str\<char8_t\>
+- `ssu` для simple_str\<char16_t\>
+- `ssw` для simple_str\<wchar_t>
+- `ssuu` для simple_str\<char32_t\>
+
+Применяется в основном для передачи строк как параметр функций, не модифицирующих переданную строку, вместо `const std::string&`,
+а также для локальных переменных при работе с частями строк.
+
+#### Второй класс — `simple_str_nt`
+(simstr::simple_str_nt)
+
+По устройству и назначению совпадает с `simple_str`, но дает гарантии нуль-терминированности строки.
+То есть если функции надо переданный параметр без изменений передать дальше как C-строку в какое то API, она должна использовать для
+параметра тип `simple_str_nt`.
+Все классы владеющих строк (simstr::sstring, simstr::lstring) могут быть преобразованы в `simple_str_nt`, так как хранят строки с завершающим нулём.
+Это позволяет писать функции с единым типом параметра, принимающим на вход любой тип владеющих строковых объектов.
+
+Алиасы:
+- `stra` для simple_str_nt\<char>
+- `strb` для simple_str_nt\<char8_t>
+- `stru` для simple_str_nt\<char16_t>
+- `strw` для simple_str_nt\<wchar_t>
+- `struu` для simple_str_nt\<char32_t>
+
+Может инициализироваться строковыми литералами:
+```cpp
+    stra text = "Text";
+```
+Длина в этом случае вычисляется сразу при компиляции. Аналогично `simple_str_nt` создается с помощью `operator""_ss`:
+
+```cpp
+    stringa result = "Count: "_ss + count;
+```
+
+#### Класс sstring (shared string).
+(simstr::sstring)
+
+Класс, умеющий хранить иммутабельную строку.
+То есть ему можно присвоить некую строку только целиком, модифицировать символы строки нельзя.
+
+Владеет строкой, управляет памятью для символов строки.
+Хранит со строками завершающий нуль, и может быть источником для `simple_str_nt`, для передачи в C-API.
+Так же, как и `simple_str`, реализует все методы, не модифицирующие строку.
+
+Алиасы:
+- `stringa` для sstring\<char>
+- `stringb` для sstring\<char8_t>
+- `stringu` для sstring\<char16_t>
+- `stringw` для sstring\<wchar_t>
+- `stringuu` для sstring\<char32_t>
+
+
+То, что хранимая строка иммутабельна, позволяет применить ряд оптимизаций:
+- Для строк, не подходящих для SSO,  использует общий разделяемый буфер с атомарным счётчиком ссылок.
+  Позволяет быстро копировать строку без необходимости блокировок доступа к содержимому буфера.
+- Нет необходимости хранить размер буфера (capacity) — всё равно мы ничего не дописываем в буфер.
+- Позволяет просто ссылаться на литералы программы, не копируя их символы в какой-либо буфер:
+    ```cpp
+	stringa str = "Hello!";       // Ничего не стоит, не копирует байты строки
+	stringa ltr = stra{"Hello!"}; // А вот тут копирует байты строки в ltr
+    ```
+
+Также в классе применяется **SSO** – Small String Optimization.
+Короткие строки помещаются внутри самого объекта во внутренний буфер.
+
+Размеры:
+
+Для 64 бит:
+- `stringa` – класс 24 байта, SSO до 23 символов.
+- `stringu` – класс 32 байта, SSO до 15 символов.
+- `stringuu` – класс 32 байта, SSO до 7 символов.
+
+Для 32 бит:
+- `stringa` – класс 16 байт, SSO до 15 символов.
+- `stringu` – класс 24 байта, SSO до 11 символов.
+- `stringuu` – класс 24 байта, SSO до 5 символов.
+
+#### Класс lstring<K, N, forShared> (local string)
+(simstr::lstring)
+
+Класс, хранящий строку и позволяющий её модифицировать.
+Владеет строкой, управляет памятью для символов строки.
+Хранит со строками завершающий нуль, и может быть источником для `simple_str_nt`, для передачи в C-API.
+Как и все остальные классы, реализует все методы, не модифицирующие строку.
+
+В качестве `N` в параметре шаблона задаётся размер внутреннего буфера для хранения символов.
+Строки длиной до N символов хранятся внутри объекта, а при превышении этого количества — аллоцируется динамический буфер,
+в который сохраняются символы. При копировании объекта все символы также всегда копируются.
+
+Если `forShare` == true и символы не помещаются в локальный буфер, то динамический буфер создается с дополнительным местом,
+так чтобы совпадать по структуре с буфером `sstring`. Тогда при перемещении `lstring` в `sstring` – переместится только указатель
+на буфер, без излишнего копирования символов.
+
+Этот класс удобен для работы со строками как локальная переменная на стеке.
+Обычно мы предполагаем примерный размер строк, с котороми будем работать, и можем создать локальную строку с буфером на стеке,
+и работать с ней. При этом не опасаясь переполнения буфера, так как в этом случае строка переключится на динамический буфер.
+
+Алиасы:
+- `lstringa<N=15>` для lsrting\<char, N, false>
+- `lstringb<N=15>` для lsrting\<char8_t, N, false>
+- `lstringu<N=15>` для lsrting\<char16_t, N, false>
+- `lstringw<N=15>` для lsrting\<wchar_t, N, false>
+- `lstringuu<N=15>` для lsrting\<char32_t, N, false>
+- `lstringsa<N=15>` для lsrting\<char, N, true>
+- `lstringsb<N=15>` для lsrting\<char8_t, N, true>
+- `lstringsu<N=15>` для lsrting\<char16_t, N, true>
+- `lstringsw<N=15>` для lsrting\<wchar_t, N, true>
+- `lstringsuu<N=15>` для lsrting\<char32_t, N, true>

+
+В этом примере вы наверняка заметили, как конкатенируются строки и задались вопросом — как же при двух сложениях считалась
+длина всего результата, чтобы выделить необходимое место сразу за один раз, без промежуточных буферов?
+
+Ответ на этот вопрос:
+
+### Строковые выражения
+Дело в том, что в библиотеке нет сложения строковых объектов как такового. Сложение выполняется для «строковых выражений».
+
+*Строковое выражение* — это любой объект произвольного типа, имеющий функции `length` и `place`.
+Функция `length` – возвращает длину строки, функция `place` – помещает символы строки в переданный ей буфер.
+
+Любая владеющая строка (simstr::sstring, simstr::lstring) может инициализироваться строковым выражением — она запрашивает у него длину,
+выделяет место для хранения символов, и передает это место строковому выражению, вызывая его функцию place.
+
+Кроме того, все входящие в `simstr` строковые выражения могут преобразовываться в стандартные строки (`std::basic_string`)
+совместимых типов символов, что позволяет применять быструю конкатенацию там, где заменить `std::string` пока невозможно.
+Совместимые типы символов - такие, которые совпадают по размеру.
+Для получения стандартной строки до C++23 используется `resize`, а потом заполнение через `data()`, начиная с C++23
+используется более оптимальный `resize_and_overwrite`.
+
+Для строковых выражений определена шаблонная функция сложения:
+```cpp
+    template<StrExpr A, StrExprForType<typename A::symb_type> B>
+    inline auto operator + (const A& a, const B& b) {
+        return strexprjoin<A, B>{a, b};
+    }
+```
+
+`strexprjoin` – шаблонный тип, который сам является строковым выражением.
+В себе он хранит ссылки на два переданных ему строковых выражения.
+При запросе длины он выдает сумму длин двух строковых выражений, а при размещении символов — сначала размещает
+в переданном буфере первое выражение, затем второе.
+```cpp
+    template<StrExpr A, StrExprForType<typename A::symb_type> B>
+    struct strexprjoin {
+        using symb_type = typename A::symb_type;
+        const A& a;
+        const B& b;
+        constexpr strexprjoin(const A& a_, const B& b_) : a(a_), b(b_){}
+        constexpr size_t length() const noexcept { return a.length() + b.length(); }
+        constexpr symb_type* place(symb_type* p) const noexcept { return b.place(a.place(p)); }
+    };
+```
+Таким образом, операция сложения строковых выражений создает объект, также являющийся строковым выражением,
+к которому также может быть применена следующая операция сложения, и который рекурсивно хранит ссылки на слагаемые части,
+каждая из которых знает свой размер и умеет размещать себя в буфере результата. И так далее, к каждому получаемому
+строковому выражению можно снова применить `operator +`, формируя цепочку из нескольких строковых выражений,
+и в итоге "материализовать" последний получившийся объект, который сначала посчитает размер всей общей памяти для
+конечного результата, а затем разместит вложенные подвыражения в один буфер.
+
+Операция сложения строковых выражений позволяет конкатенировать строковые выражения разных, но совместимых типов.
+То есть в одном выражении вы можете смешивать `""` и `u8""`, в Linux `L""` и `U""`, в Windows `L""` и `u""`
+типы символов. Примеры есть в `tests\test_str.cpp TEST(SimStr, StrPrintfU8)`.
+
+Все строковые типы библиотеки сами являются строковыми выражениями, то есть могут служить слагаемыми в конкатенациях
+строковых выражений.
+
+Также `operator+` определён для строковых выражений и строковых литералов, строковых выражений и чисел (числа конвертируются
+в десятичное представление), а также вы можете сами добавить желаемые типы.
+
+Пример:
+```cpp
+	stringa text = header + " count=" + count + ", done";
+```
+
+Для стандартных строк (`std::basic_string` и `std::basic_string_view`) также сделаны операторы сложения со строковыми
+выражениями, поэтому переменные этих типов также напрямую участвовать в операциях конкатенирования.
+Однако cтандартные строки могут напрямую участвовать в строковых выражениях только когда
+другой операнд тоже является строковым выражением. Если другой операнд - не строковое выражение,
+используйте перед стандартными строками унарный `operator+`, чтобы превратить `std::basic_string` или `std::basic_string_view`
+в строковое выражение.
+
+Пример:
+```cpp
+std::string make_text(const std::string& text, std::string_view what, int count) {
+    //     + превращает text в строковое выражение, а дальше они уже складываются между собой
+    return +text + " " + count + " " + what + e_if(count > 1, "s");
+    //                                 what участвует уже напрямую как операнд со стороковым выражением
+}
+std::string make_answer(const std::string& text, std::string_view what, int count) {
+    return "Answer is: " + +text + " " + count + " " + what + e_if(count > 1, "s");
+    //                     + превращает text в строковое выражени, и оно может быть сложено с предыдущим строковым литералом
+}
+```
+То есть унарный `+` нужен только где-то в начале выражения, если другой операнд не строковое выражение.
+
+Существует несколько типов строковых выражений "из коробки", для выполнения различных операций со строками:
+
+#### expr_spaces<ТипСимвола, КоличествоСимволов, Символ = ' '>{}
+Выдает строку длиной КоличествоСимволов,  заполненную заданным символом. Количество символов и символ - константы времени
+компиляции. Для некоторых случаев есть сокращенная запись:
+
+    e_spca(КоличествоСимволов) - строка char пробелов
+    e_spcw(КоличествоСимволов) - строка w_char пробелов
+
+#### expr_pad<ТипСимвола>{КоличествоСимволов, Символ = ' '}
+Выдает строку длиной КоличествоСимволов, заполненную заданным символом.
+Количество символов и символ могут задаваться в рантайме. Сокращенная запись:
+
+    e_c(КоличествоСимволов, Символ)
+
+#### e_repeat{Str, count}
+Генерирует повторение строкового литерала или выражения `Str` `count` раз.
+
+    e_repeat("aa", 10);
+
+#### e_choice(bool Condition, StrExpr1, StrExpr2)
+Если Condition == true, результат будет равен StrExpr1, иначе StrExpr2.
+
+#### e_if(bool Condition, StrExpr1)
+Если Condition == true, результат будет равен StrExpr1, иначе пустая строка.
+
+#### expr_num<ТипСимвола>(ЦелоеЧисло)
+Конвертирует число в десятичное представление. Редко используется, так как для строковых выражений и чисел
+переопределен оператор "+", и число можно просто написать как `text + number`;
+
+#### expr_real<ТипСимвола>(ВещественноеЧисло)
+конвертирует число в десятичное представление. Редко используется, так как для строковых выражений и чисел
+переопределен оператор "+", и число можно просто написать как `text + number`;
+
+#### e_join<bool ПослеПоследнего = false, bool ТолькоНеПустые = false>(контейнер, "Разделитель")
+Конкатенирует все строки в контейнере, используя разделитель. Если ПослеПоследнего == true,
+то разделитель добавляется и после последнего элемента контейнера, иначе только между элементами.
+Если ТолькоНеПустые == true, то пустые строки пропускаются без добавления разделителя.
+
+#### e_repl(ИсходнаяСтрока, "Искать", "Заменять")
+Заменяет в исходной строке вхождения "Искать" на "Заменять".
+Шаблоны поиска и замены - строковые литералы времени компиляции.
+
+#### expr_replaced<ТипСимвола>{ИсходнаяСтрока, Искать, Заменять}
+Заменяет в исходной строке вхождения Искать на Заменять.
+Шаблоны поиска и замены - могут быть любыми строковыми объектами в рантайме.
+
+#### empty_expr<ТипСимвола>
+Выдает пустую строку. Сокращённая запись — eea, eeu, eew, eeuu. Применяется если формирование строки начинается с числа и строкового литерала:
+```cpp
+	str = eea + count + " times.";
+```
+так как оператор сложения определён только для сложения строкового выражения и числа.
+Также замечу, что существует `operator""_ss`, который превращает строковый литерал в объект `simple_str_nt`, который уже является строковым выражением:
+```cpp
+	str = "Count = "_ss + count;
+    ...
+    str = count + " times."_ss;
+```
+
+#### Свои строковые выражения
+Вы можете сами создавать свои типы строковых выражений для оптимального формирования строк в нужных вам целях и алгоритмах.
+Для этого просто создайте тип с методами `length`, `place` и `typename symb_type`.
+Примеры создания и использования из реальных проектов:
+
+```cpp
+/* Сформировать строку в JSON формате, в 16 битных символах */
+struct expr_json_str {
+    using symb_type = u16s;

+    expr_json_str(ssu t);
+};
+
+inline expr_json_str::expr_json_str(ssu t) : text(t) {

+
+    for (size_t i = 0; i < text.length(); i++) {
+        switch (*ptr++) {
+        case '\b':

+    }
+    l = text.len + add;
+}
+
+inline u16s* expr_json_str::place(u16s* ptr) const noexcept {
+    const u16s *r = text.symbols();

+        std::char_traits<u16s>::copy(ptr, r, lenOfTail);
+        ptr += lenOfTail;
+    }
+    return ptr;

+
+ВНИМАНИЕ: обычно поля в объектах строковых выражений являются ссылками на исходные данные.
+И ссылки эти почти всегда ведут на локальные или временные объекты. Поэтому крайне рискованно возвращать строковые выражения
+из функций — надо сто раз проверить, что в них не попали ссылки на локальные или временные переменные.
+Возьмите за правило — можно легко передавать строковые выражения в функции, и опасно возвращать их из функций.
+Лучше при возврате материализовать строковое выражение в строковый объект, содержащий итоговую строку.
+При желании тип возвращаемой строки можно задать шаблонным параметром.
+
+
+### Класс chunked_string_builder
+
+Предназначен для конкатенации множества строк.
+Когда вам нужно последовательно формировать длинный текст из множества небольших кусочков (например, формируете html ответ
+и т. п.) - последовательно складывать всё в один строковый объект крайне неоптимально — будет много переаллокаций и
+перекопирования уже накопленных символов. В этом случае удобно использовать chunked_string_builder — всё, что он умеет,
+это прибавлять строку к накопленным символам. Однако делает он это не в единый последовательный буфер памяти, а в отдельные
+буфера, не меньше чем заданное выравнивание. При заполнении очередного буфера он просто создает ещё один буфер и продолжает
+складывать данные в него.
+
+То есть допустим вы задали выравнивание 1024.
+Добавили несколько строк, заполнили буфер  на 100 символов. И добавляете строку длинной 3000 символов.
+При этом 924 символа скопируются в первый буфер, заполнив его до конца.
+Для оставшихся 2076 создастся буфер размером 3072 символа, и они скопируются в него, в нём останется место для 996 символов.
+Так последовательно каждый буфер заполняется до конца, и имеет размер кратный заданному выравниванию.
+Таким образом избегаются переаллокации и перекопирование обработанных символов.
+
+После окончательного заполнения вы можете работать с накопленными данными — либо слить все буфера в одну последовательную
+строку (размер для буфера которой вы теперь уже знаете), либо перебирать их по отдельности, например, посылая эти буфера
+в сеть. Либо последовательно копируя данные в буфер заданного размера.

 [![CMake on multiple platforms](https://github.com/orefkov/simstr/actions/workflows/cmake-multi-platform.yml/badge.svg)](https://github.com/orefkov/simstr/actions/workflows/cmake-multi-platform.yml)
 
-Версия 1.0.
+Version 1.9.1
 
-В этой библиотеке содержится реализация нескольких видов строковых объектов и различных алгоритмов для работы со строками.
-
-Цель библиотеки - сделать работу со строками в С++ такой же простой и лёгкой, как во множестве других языков, особенно
-скриптовых, но при этом сохранив оптимальность и производительность на уровне С и C++, и даже улучшив их.
-
-Не секрет, что работа со строками в С++ зачастую доставляет боль. Класс `std::string` часто неудобен либо неэффективен.
-Многих функций, обычно необходимых при работе со строками, просто нет, и их каждому приходится писать самому.
-
-Эта библиотека не делалась как универсальный комбайн, который "может всё", я реализовывал то, что мне приходилось
-использовать в работе, стараясь сделать это наиболее эффективным способом, и скромно надеюсь, что кое-что у меня получилось
-и пригодится другим людям, либо напрямую, либо как источник идей.
-
-Библиотека не претендует на роль "поменял хедер и всё заработало лучше". Многие методы я старался делать совместимыми
-с `std::string` и `std::string_view`, но особо с этим не заморачивался. Переписывание старого кода на работу с simstr
-потребует некоторых усилий, но уверяю, что они окупятся. А новый код писать с её применением легко и доставляет удовольствие :)
-
-Основное отличие simstr от std::string - для работы со строками используется не единый универсальный класс, а несколько
-видов объектов, каждый из которых хорош для своих целей, и при этом хорошо взаимодействующих друг с другом.
-Если вы активно использовали std::string_view и понимали, в чём его преимущество и недостатки по сравнению с std::string,
-то подход simstr вам также будет понятен.
-
-## Основные возможности библиотеки
-- Строки `char`, `char16_t`, `char32_t`, `wchar_t`.
-- Прозрачное преобразование строк из одного типа символов в другой, с автоматической конвертацией между UTF-8, UTF-16, UTF-32,
-  используя [simdutf](https://github.com/simdutf/simdutf).
-- Расширяемая система "Строковых выражений". Позволяет эффективно реализовать преобразование и сложение (конкатенацию) строк, литералов,
-  чисел и возможно других объектов.
-- Строковые функции:
-  - Получение подстрок.
-  - Поиск подстрок и символов - с начала или с конца строки.
-  - Различный тримминг строк - справа, слева, везде, по пробельным символам, по заданным символам.
-  - Замена подстрок.
-  - Замена набора символов на набор соответствующих подстрок.
-  - Слияние (join) контейнеров строк в единую строку, с заданием разделителей и опций - "пропускать пустые", "разделитель после последней".
-  - Разбиение (split) строк на части по заданному разделителю. Разбиение возможно сразу в контейнер со строками, либо вызовом функтора для
-    каждой подстроки, либо путем итерации с помощью итератора `Splitter`.
-- Интеграция с функциями форматирования `format` и `sprintf` (с автоматическим увеличением буфера).
-  Форматирование возможно для строк `char`, `wchar_t` и строк, совместимых с `wchar_t` по размеру.
-  То есть под Windows это `char16_t`, под Linux - `char32_t`. Писать свою библиотеку форматирования не входило в мои замыслы.
-- Парсинг целых чисел с возможностью "тонкой" настройки при компиляции - можно задавать опции проверки переполнения,
-  пропуск пробельных символов, конкретное основание счисления либо автовыбор по префиксам `0x`, `0`, `0b`, `0o`,
-  допустимость знака `+`. Парсинг реализован для всех видов строк и символов.
-- Парсинг double пока реализован вызовом стандартной библиотеки и работает только для строк `char`, `wchar_t` и совместимых с
-  `wchar_t` по размеру типов.
-- Содержится минимальная поддержка Unicode при преобразовании `upper`, `lower` и регистро-независимом сравнении строк.
-  Работает только для символов первой плоскости Unicode (до 0xFFFF), а при смене регистра не учитываются случаи, когда один code point
-  может преобразовываться в несколько, то есть преобразование регистра символов соответствует `std::towupper`, `std::towlower` для unicode локали, только быстрее и может работать с любым видом символов.
-- Реализован `hash map` для ключей строкового типа, на базе `std::unordered_map`, с возможностью более эффективного хранения и
-  сравнения ключей по сравнению с ключами `std::string`. Поддерживается возможность регистро-независимого сравнения ключей (Ascii или
-  минимальный Unicode (см. предыдущий пункт)).
-
-## Основные объекты библиотеки
-- simple_str&lt;K> - самая простая строка (или кусок строки), иммутабельная, не владеющая, аналог `std::string_view`.
-- simple_str_nt&lt;K> - то же самое, только заявляет, что заканчивается 0. Для работы со сторонними C-API.
-- sstring&lt;K> - shared string, иммутабельная, владеющая, с разделяемым буфером символов, поддержка SSO.
-- lstring&lt;K, N> - local string, мутабельная, владеющая, с задаваемым размером SSO буфера.

-## Использование
-`simstr` состоит из трёх заголовочных файлов и двух исходников. Можно подключать как CMake проект через `add_subdirectory` (библиотека `simstr`),
-можно просто включить файлы в свой проект. Для сборки также требуется [simdutf](https://github.com/simdutf/simdutf) (при использовании CMake
-скачивается автоматически).
-
-Для работы `simstr` требуется компилятор стандарта не ниже С++20 - используются концепты и std::format.
-Работа проверялась под Windows на MSVC-19 и Clang-19, под Linux - на GCC-13 и Clang-21.
-Также проверялась работа в WASM, сборка в Emscripten 4.0.6, Clang-21.
+<h2>Speed up your work with strings by 2-10 times!</h2>
 
 
-## Бенчмарки
-Бенчмарки производятся с использованием фреймворка [Google benchmark](https://github.com/google/benchmark).
-Постарался сделать замеры для наиболее типичных операций, встречающихся в обычной работе. Я проводил замеры на своём оборудовании, под
-Windows и Linux (в WSL), с использованием компиляторов MSVC, Clang, GCC. Сторонние результаты приветствуются.
-Также проводил замеры в WASM, сборка в Emscripten. Обращаю внимание, что под WASM в Emscripten собирается 32-битная сборка, а значит,
-размеры буферов SSO в объектах меньше.
+This library contains a modern implementation of several types of string objects and various algorithms for working with strings.

+## Brief Description
+The goal of the library is to make working with strings in C++ as simple and easy as in many other languages, especially
+scripting languages, while maintaining optimality and performance at the level of C and C++, and even improving them.
 
-## Примеры использования
-Пока отдельных примеров использования не подготовлено, можно посмотреть тексты [тестов](tests/test_str.cpp),
-[бенчмарков](bench/bench_str.cpp), и [утилиты подготовки html](bench/process_result.cpp) из результатов бенчмарков.
-Также simstr используется в моём проекте [v8sqlite](https://github.com/orefkov/v8sqlite)
+It's no secret that working with strings in C++ often causes pain. The `std::string` class is often inconvenient or inefficient.
+Many functions that are usually necessary when working with strings are simply not there, and everyone has to write them themselves.
+Even concatenating `std::string` and `std::string_view` became possible only with C++26.
+That's why I started creating this library for myself around 2012, and now I'm ready to share it with all C++ developers.
 
-## Сгенерированная документация
-[Находится здесь](https://snegopat.ru/simstr/docs/)
+This library was not made as a universal combine that "can do everything", I implemented what I had to
+use in my work, trying to do it in the most efficient way, and I modestly hope that I have succeeded in something
+and will be useful to other people, either directly or as a source of ideas.
+
+The library contains two parts:
+- Implementation of [*"String Expressions"*](https://orefkov.github.io/simstr/articles/fast_concat.html) and algorithms for working
+  with constant strings.\
+  To use this part, just take the file `"include/simstr/strexpr.h"` and write in your code
+  ```cpp
+  #include "path/to file/strexpr.h"
+  ```
+  This will allow you to use powerful and fast *"string expressions"* for concatenation and string construction for standard string types
+  (`std::basic_string`, `std::basic_string_view`), as well as simplified versions of the `simple_str` and
+  `simple_str_nt` classes, which implement all those string algorithms of the library that do not require storing or modifying strings.
+  Since this is a header-only part, it does not include working with UTF encodings and simplified Unicode.
+- The full version, requiring the connection of the entire library (`"include/simstr/sstring.h"`), adds its string types with
+  the ability to store and modify strings, works with UTF encodings and simplified Unicode.
+
+The library does not pretend to be a "changed header and everything worked better" - it gets along well with standard strings
+and does not change the behavior of existing code working with them. I tried to make many methods in it compatible
+with `std::string` and `std::string_view`, but I didn't bother with this much. Rewriting your code to work with `simstr`
+will require some effort, but I assure you that it will pay off. And thanks to compatibility with standard strings, this work can be done
+in stages, in small pieces. Creating new code for working with strings with its use is easy and enjoyable :)
+
+
+The main difference between `simstr` and `std::string` is that not a single universal class is used for working with strings, but several
+types of objects, each of which is good for its own purposes, and at the same time interact well with each other.
+If you actively used `std::string_view` and understood its advantages and disadvantages compared to `std::string`,
+then the `simstr` approach will also be clear to you.
+
+## Key Features of the Library
+When using only `#include "simstr/strexpr.h"`:
+- Support for working with strings `char`, `char8_t`, `char16_t`, `char32_t`, `wchar_t`.
+- Powerful and extensible *"String Expressions"* system.
+  Allows you to efficiently implement the conversion and addition (concatenation) of strings, string literals, numbers (and possibly other objects),
+  achieving significant acceleration of string operations.
+  Compatible with both `simstr` string objects and standard strings (`std::basic_string`,
+  `std::basic_string_view`), which allows you to apply fast concatenation even where it is not yet possible to abandon standard strings.
+  Also allows you to mix strings of compatible character types in operations.
+- Constant string functions (do not change the original string):
+  - Getting substrings.
+  - Comparing strings, comparing strings ignoring the case of ASCII characters.
+  - Searching for substrings and characters - from the beginning or from the end of the string.
+  - Various trimming of strings - right, left, everywhere, by whitespace characters, by specified characters.
+  - Replacing substrings (creating a copy of the string with the replacement).
+  - Replacing a set of characters with a set of corresponding substrings (creating a copy of the string with the replacement).
+  - Merging (join) containers of strings into a single string, with specifying separators and options - "skip empty", "separator after last".
+  - Splitting strings into parts by a specified delimiter. Splitting is possible immediately into a container with strings, or by calling a functor for
+    each substring, or by iterating using the `Splitter` iterator.
+- Functions for modifying standard strings with string expressions:
+  - str::append, str::prepend, str::insert, str::change - change str::string with string expressions,
+    for example `str::append(text, "count = "_ss + count)`.
+  - str::replace - replaces occurrences of the search substring with a replacement string or string expression.
+    If the substring is not found, the string expression is not even evaluated.
+  - str::make_ascii_upper, str::make_ascii_lower - change the case of ASCII characters.
+- Parsing of integers from a "piece of string" (does not require null termination) with the possibility of "fine" tuning during compilation -
+  you can set options for checking for overflow, skipping whitespace characters, a specific radix, or auto-select by
+  prefixes `0x`, `0`, `0b`, `0o`, the `+` sign is allowed. Parsing is implemented for all types of strings and characters.
+- Parsing double from a "piece of string" for `char` and `char8_t`.
+
+When using the full version of the library:
+- Everything that is listed above, plus
+- Parsing double from a "piece of string" for all types of characters.
+- Additional efficient string objects - `sstring` (shared string), `lstring` (local string).
+- `lstring` - supports many mutable operations with strings - various replacements, insertions, deletions, etc.
+  Allows you to set the size for the internal character buffer, which can turn *Small String Optimization* into *Big String Optimization* :).
+- Transparent conversion of strings from one character type to another, with automatic conversion between UTF-8, UTF-16, UTF-32,
+  using [simdutf](https://github.com/simdutf/simdutf). Strings of "compatible" types are converted by simple copying:
+  `char <-> char8_t`, `wchar_t <-> char32_t` in Linux, `wchar_t <-> char16_t` in Windows.
+- Integration with `format` and `sprintf` formatting functions (with automatic buffer increase).
+  Formatting is possible for `char`, `wchar_t` strings and strings compatible with them in size.
+  That is, under Windows it is `char8_t`, `char16_t`, under Linux - `char8_t`, `char32_t` (writing my own formatting library for all types of
+  characters was not part of my plans).
+- Contains minimal Unicode support when converting `upper`, `lower` and case-insensitive string comparison.
+  Works only for characters of the first Unicode plane (up to 0xFFFF), and when changing the case, cases are not taken into account when one code point
+  can be converted into several, that is, the case conversion of characters corresponds to `std::towupper`, `std::towlower` for the unicode locale, only faster and can work with any type of characters.
+- Implemented `hash map` for string type keys, based on `std::unordered_map`, with the possibility of more efficient storage and
+  comparison of keys compared to `std::string` keys. Supports the possibility of case-insensitive comparison of keys (Ascii or
+  minimal Unicode (see previous paragraph)).
+
+## Benchmarks
+Benchmarks are performed using the [Google benchmark](https://github.com/google/benchmark) framework.
+I tried to make measurements for the most typical operations that occur in normal work. I took measurements on my equipment, under
+Windows and Linux (in WSL), using MSVC, Clang, GCC compilers. Third-party results are welcome.
+I also took measurements in WASM, built in Emscripten. I draw attention to the fact that a 32-bit build is built under WASM in Emscripten, which means that
+the sizes of SSO buffers in objects are smaller.
+
+On the [release page](https://github.com/orefkov/simstr/releases) you can download binary builds of benchmarks and run them on your equipment.
+
+You can also run the [Emscripten build of benchmarks](https://orefkov.github.io/simstr/bench/benchStr.html) directly in the browser.

+
+## String Expressions
+These are special objects that efficiently implement string concatenation using `operator+`.
+The main principle, due to which efficient work is achieved - no matter how many operands are included in the entire expression,
+no temporary (intermediate) strings are created, the total length of the entire result is calculated only once,
+memory is allocated for the result character buffer only once, after which the characters are copied directly to the result buffer
+to its place. No memory reallocations, no moving characters in various intermediate buffers - everything is
+as efficient as possible. Thanks to the capabilities of C++ templates and operator overloading, the expression is written as close as possible
+to the usual syntax for adding strings.
+In addition, there are special overloads for adding string objects and string literals, strings and numbers,
+for copying with replacement, for merging containers of strings and much more.
+Thanks to the extensibility of this system, it is possible to create new options for building strings, and development is constantly ongoing.
+
+All string objects from `simstr` are themselves string expressions, that is, they can be used in concatenation operations
+string expressions directly. Standard strings (`std::basic_string`, `std::basic_string_view`) can also serve as operands
+in addition operations with string expressions. Or they can be easily converted into a string expression by placing them in front of them
+unary `+`.
+
+## Usage Examples
+### Adding strings with numbers
+```cpp
+std::string s1 = "start ";
+int i;
+....
+// Was
+    std::string str = s1 + std::to_string(i) + " end";
+// Became
+    std::string str = +s1 + i + " end";
+```
+`+s1` - converts `std::string` into an object - a string expression for which there is an efficient concatenation with numbers and string literals.
+
+According to benchmarks, [acceleration 1.6 - 2 times](https://orefkov.github.io/simstr/results.html#bs70109915512075798510).
+
+### Adding strings with numbers in hex format
+```cpp
+....
+// Was

+### Adding multiple literals and searching in `std::string_view`

+// It was like this

+    // before C++26 we can not concatenate string and string_view...
+    return src.find("\n- "s + std::string{name} + " -\n");

+
+// And when using the full library, you can do this
+size_t find_pos(ssa src, ssa name) {
+    // In this version, if the result of the concatenation fits into 207 characters, it is produced in a buffer on the stack,
+    // without allocation and deallocation of memory, acceleration several times. And only if the result is longer than 207 characters -
+    // there will be only one allocation, and the concatenation will be immediately into the allocated buffer, without copying characters.
+    return src.find(lstringa<200>{"\n- " + name + " -\n"});
+}
+```
+`ssa` - alias for `simple_str<char>` - analogue of `std::string_view`, allows you to accept as a function parameter with minimal costs
+any string object that does not need to be modified or passed to the C-API: `std::string`, `std::string_view`, `"string literal"`,
+`simple_str_nt`, `sstring`, `lstring`. Also, since it is also a "string expression", it allows you to easily
+build concatenations with its participation.

+
+## Usage
+The library can be used partially, simply by taking the file `"include/simstr/strexpr.h"` and including it in your sources
+```cpp
+#include "include/simstr/strexpr.h"
+```
+This will only connect string expressions and simplified implementations of `simple_str` and `simple_str_nt`, without UTF and Unicode functions.
+
+The full version of the `simstr` library consists of three header files and two source files.
+You can connect as a CMake project via `add_subdirectory` (the `simstr` library),
+you can simply include the files in your project. Building also requires [simdutf](https://github.com/simdutf/simdutf) (when using CMake
+it is downloaded automatically).
+
+### Connection via FetchContent
+```
+function(add_simstr)
+    set(SIMSTR_BUILD_TESTS OFF)
+    set(SIMSTR_BENCHMARKS OFF)
+    FetchContent_Declare(
+        simstr
+        GIT_REPOSITORY https://github.com/orefkov/simstr.git
+        GIT_SHALLOW TRUE
+        GIT_TAG tags/rel1.9.1# Specify the desired release
+        FIND_PACKAGE_ARGS NAMES simstr 1.9.1
+    )
+    FetchContent_MakeAvailable(simstr)
+endfunction()
+
+add_simstr()
+
+target_link_libraries(<your target> PUBLIC simstr::simstr)
+```
+
+The library is also included in [vcpkg](https://vcpkg.io), connected as `orefkov-simstr`.
+
+For `simstr` to work, a compiler of the standard no lower than C++20 is required - concepts and std::format are used.
+The work was checked under Windows on MSVC-19 and Clang-19, under Linux - on GCC-13 and Clang-21.
+The work in WASM was also checked, built in Emscripten 4.0.6, Clang-21.
+
+## Convenient Debugging
+Along with the library, two files are supplied that make viewing simstr string objects in debuggers
+more convenient.\
+More details are described [here](for_debug/readme.md).

+# simstr - библиотека строковых объектов и функций
+<span class="obfuscator"><a href="readme.md">On English | По-английски</a></span>
+
+[![CMake on multiple platforms](https://github.com/orefkov/simstr/actions/workflows/cmake-multi-platform.yml/badge.svg)](https://github.com/orefkov/simstr/actions/workflows/cmake-multi-platform.yml)
+
+Версия 1.9.1
+
+<h2>Ускорь работу со строками в 2-10 раз!</h2>
+
+
+В этой библиотеке содержится современная реализация нескольких видов строковых объектов и различных алгоритмов для работы со строками.
+## Сгенерированная документация
+[Находится здесь](https://orefkov.github.io/simstr/docs_ru/)
+
+## Краткое описание
+Цель библиотеки - сделать работу со строками в С++ такой же простой и лёгкой, как во множестве других языков, особенно
+скриптовых, но при этом сохранив оптимальность и производительность на уровне С и C++, и даже улучшив их.
+
+Не секрет, что работа со строками в С++ зачастую доставляет боль. Класс `std::string` часто неудобен либо неэффективен.
+Многих функций, обычно необходимых при работе со строками, просто нет, и их каждому приходится писать самому.
+Даже элементарно конкатенировать `std::string` и `std::string_view` стало возможно только с C++26.
+Именно поэтому я начал примерно в 2012 году создавать для себя эту библиотеку, и теперь готов поделится ею со всеми C++ разработчиками.
+
+Эта библиотека не делалась как универсальный комбайн, который "может всё", я реализовывал то, что мне приходилось
+использовать в работе, стараясь сделать это наиболее эффективным способом, и скромно надеюсь, что кое-что у меня получилось
+и пригодится другим людям, либо напрямую, либо как источник идей.
+
+Библиотека содержит две части:
+- Реализация [*"Строковых выражений"*](https://orefkov.github.io/simstr/articles/fast_concat_ru.html) и алгоритмов работы
+  с константными строками.\
+  Для использования этой части достаточно просто взять файл `"include/simstr/strexpr.h"` и написать в своём коде
+  ```cpp
+  #include "путь/к файлу/strexpr.h"
+  ```
+  Это позволит вам для стандартных строковых типов (`std::basic_string`, `std::basic_string_view`) использовать
+  мощные и быстрые *"строковые выражения"* для конкатенации и построения строк, а также упрощенные варианты классов `simple_str` и
+  `simple_str_nt`, которые реализуют все те строковые алгоритмы библиотеки, которые не требуют хранения или модификации строк.
+  Так как это header-only часть, она не включает в себя работу с UTF-кодировками и упрощённый Unicode.
+- Полная версия, требующая подключения всей библиотеки (`"include/simstr/sstring.h"`), добавляет свои строковые типы с
+  возможностями хранения и модификации строк, работает с UTF-кодировками и упрощённым Unicode.
+
+Библиотека не претендует на роль "поменял хедер и всё заработало лучше" - она прекрасно уживается вместе со стандартными строками
+и не меняет поведение уже существующего кода, работающего с ними. Многие методы в ней я старался делать совместимыми
+с `std::string` и `std::string_view`, но особо с этим не заморачивался. Переписывание вашего кода на работу с `simstr`
+потребует некоторых усилий, но уверяю, что они окупятся. А благодаря совместимости со стандартными строками эту работу можно делать
+поэтапно, небольшими кусками. Новый же код работы со строками создавать с её применением легко и доставляет удовольствие :)
+
+
+Основное отличие `simstr` от `std::string` - для работы со строками используется не единый универсальный класс, а несколько
+видов объектов, каждый из которых хорош для своих целей, и при этом хорошо взаимодействующих друг с другом.
+Если вы активно использовали `std::string_view` и понимали, в чём его преимущества и недостатки по сравнению с `std::string`,
+то подход `simstr` вам также будет понятен.
+
+## Основные возможности библиотеки
+При использовании только `#include "simstr/strexpr.h"`:
+- Поддержка работы со строками `char`, `char8_t`, `char16_t`, `char32_t`, `wchar_t`.
+- Мощная и расширяемая система *"Строковых выражений"*.
+  Позволяет эффективно реализовать преобразование и сложение (конкатенацию) строк, строковых литералов, чисел (и возможно других объектов),
+  добиваясь значительного ускорения строковых операций.
+  Совместима как со строковыми объектами `simstr`, так и со стандартными строками (`std::basic_string`,
+  `std::basic_string_view`), что позволяет применять быструю конкатенацию и там, где пока не получается отказаться от стандартных строк.
+  Тоже позволяет смешивать в операциях строки совместимых типов символов.
+- Константные строковые функции (не меняют исходную строку):
+  - Получение подстрок.
+  - Сравнение строк, сравнение строк без учёта регистра ASCII-символов.
+  - Поиск подстрок и символов - с начала или с конца строки.
+  - Различный тримминг строк - справа, слева, везде, по пробельным символам, по заданным символам.
+  - Замена подстрок (созданием копии строки с заменой).
+  - Замена набора символов на набор соответствующих подстрок (созданием копии строки с заменой).
+  - Слияние (join) контейнеров строк в единую строку, с заданием разделителей и опций - "пропускать пустые", "разделитель после последней".
+  - Разбиение (split) строк на части по заданному разделителю. Разбиение возможно сразу в контейнер со строками, либо вызовом функтора для
+    каждой подстроки, либо путем итерации с помощью итератора `Splitter`.
+  - Создании копии со сменой регистра ASCII символов.
+- Функции модификации стандартных строк строковыми выражениями:
+  - str::append, str::prepend, str::insert, str::change - меняют str::string строковыми выражениями,
+    например `str::append(text, "count = "_ss + count)`.
+  - str::replace - заменяет вхождения искомой подстроки на строку замены или строковое выражение.
+    Если подстрока не найдена, строковое выражение даже не вычисляется.
+  - str::make_ascii_upper, str::make_ascii_lower - смена регистра ASCII символов.
+- Парсинг целых чисел из "куска строки" (не требует нуль-терминированности) с возможностью "тонкой" настройки при компиляции -
+  можно задавать опции проверки переполнения, пропуск пробельных символов, конкретное основание счисления либо автовыбор по
+  префиксам `0x`, `0`, `0b`, `0o`, допустимость знака `+`. Парсинг реализован для всех видов строк и символов.
+- Парсинг double из "куска строки" для `char` и `char8_t`.
+
+При использовании полной версии библиотеки:
+- Всё то же, что и перечислено выше, плюс
+- Парсинг double из "куска строки" для всех типов символов.
+- Дополнительные эффективные строковые объекты - `sstring` (shared string), `lstring` (local string).
+- `lstring` - поддерживает множество мутабельных операций со строками - различные замены, вставки, удаления и т.п.
+  Позволяет задавать размер для внутреннего буфера символов, что может превращать *Small String Optimization* в *Big String Optimization* :).
+- Прозрачное преобразование строк из одного типа символов в другой, с автоматической конвертацией между UTF-8, UTF-16, UTF-32,
+  используя [simdutf](https://github.com/simdutf/simdutf). Строки "совместимых" типов преобразуются простым копированием:
+  `char <-> char8_t`, `wchar_t <-> char32_t` в Linux, `wchar_t <-> char16_t` в Windows.
+- Интеграция с функциями форматирования `format` и `sprintf` (с автоматическим увеличением буфера).
+  Форматирование возможно для строк `char`, `wchar_t` и строк, совместимых с ними по размеру.
+  То есть под Windows это `char8_t`, `char16_t`, под Linux - `char8_t`, `char32_t` (писать свою библиотеку форматирования для всех видов
+  символов не входило в мои замыслы).
+- Содержится минимальная поддержка Unicode при преобразовании `upper`, `lower` и регистро-независимом сравнении строк.
+  Работает только для символов первой плоскости Unicode (до 0xFFFF), а при смене регистра не учитываются случаи, когда один code point
+  может преобразовываться в несколько, то есть преобразование регистра символов соответствует `std::towupper`, `std::towlower` для unicode локали, только быстрее и может работать с любым видом символов.
+- Реализован `hash map` для ключей строкового типа, на базе `std::unordered_map`, с возможностью более эффективного хранения и
+  сравнения ключей по сравнению с ключами `std::string`. Поддерживается возможность регистро-независимого сравнения ключей (Ascii или
+  минимальный Unicode (см. предыдущий пункт)).
+
+## Бенчмарки
+Бенчмарки производятся с использованием фреймворка [Google benchmark](https://github.com/google/benchmark).
+Постарался сделать замеры для наиболее типичных операций, встречающихся в обычной работе. Я проводил замеры на своём оборудовании, под
+Windows и Linux (в WSL), с использованием компиляторов MSVC, Clang, GCC. Сторонние результаты приветствуются.
+Также проводил замеры в WASM, сборка в Emscripten. Обращаю внимание, что под WASM в Emscripten собирается 32-битная сборка, а значит,
+размеры буферов SSO в объектах меньше.
+
+На [странице релизов](https://github.com/orefkov/simstr/releases) вы можете скачать бинарные сборки бенчмарков и запустить их на своём оборудовании.
+
+Также вы можете запустить [Emscripten сборку бенчмарков](https://orefkov.github.io/simstr/bench/benchStr.html) прямо в браузере.

+## Строковые выражения
+Это специальные объекты, которые эффективно реализуют конкатенацию строк, с помощью `operator+`.
+Главный принцип, за счёт которого достигается эффективная работа - сколько бы операндов не входило во всё выражение,
+никаких временных (промежуточных) строк не создаётся, общая длина всего результата подсчитывается только один раз,
+один раз выделяется память под буфер символов результата, после чего символы копируются сразу в буфер результата
+на своё место. Никаких перевыделений памяти, никакого передвигания символов в различных промежуточных буферах - всё
+максимально эффективно. Благодаря возможностям шаблонов C++ и перегрузке операторов, выражение пишется максимально
+приближённо к обычному синтаксису сложения строк.
+Кроме того, есть специальные перегрузки для сложения строковых объектов и строковых литералов, строк и чисел,
+для копирования с заменой, для слияния контейнеров строк и многое другое.
+Благодаря расширяемости этой системы - возможно создание новых вариантов построения строк, развитие постоянно продолжается.
+
+Все строковые объекты из `simstr` - сами являются строковыми выражениями, то есть их можно использовать в операциях конкатенации
+строковых выражений напрямую. Стандартные строки (`std::basic_string`, `std::basic_string_view`) - тоже могут служить операндами
+в операциях сложения со строковыми выражениями. Либо их можно легко преобразовать в строковое выражение, поставив перед ними
+унарный `+`.
+
+## Примеры использования
+### Сложение строк с числами
+```cpp
+std::string s1 = "start ";
+int i;
+....
+// Было
+    std::string str = s1 + std::to_string(i) + " end";
+// Стало
+    std::string str = +s1 + i + " end";
+```
+`+s1` - преобразует `std::string` в объект - строковое выражение, для которого есть эффективная конкатенация с числами и строковыми литералами.

+```cpp

+// Было
+    std::string str = s1 + std::format("0x{:x}", i) + " end";
+// Стало
+    std::string str = +s1 + e_hex<HexFlags::Short>(i) + " end";
+```

+
+### Сложение нескольких литералов и поиск в `std::string_view`
+```cpp
+// Было так
+size_t find_pos(std::string_view src, std::string_view name) {
+    // before C++26 we can not concatenate string and string_view...
+    return src.find("\n- "s + std::string{name} + " -\n");
+}
+// При использовании только "strexpr.h" стало так
+size_t find_pos(ssa src, ssa name) {
+    return src.find(std::string{"\n- " + name + " -\n"});
+}
+
+// А при использовании полной библиотеки можно сделать так
+size_t find_pos(ssa src, ssa name) {
+    // В этом варианте если результат конкатенации вмещается в 207 символов - она производится в буфере на стеке,
+    // без алокации и освобождения памяти, ускорение в несколько раз. И только если результат длиннее 207 символов -
+    // будет всего одна аллокация, и конкатенация будет сразу в алоцированный буфер, без перекопирования символов.
+    return src.find(lstringa<200>{"\n- " + name + " -\n"});
+}
+```
+`ssa` - псевдоним для `simple_str<char>` - аналог `std::string_view`, позволяет с минимальными расходами принимать параметром функции
+любой строковый объект, который не нужно модифицировать или передавать в C-API: `std::string`, `std::string_view`, `"строковый литерал"`,
+`simple_str_nt`, `sstring`, `lstring`. Также так как он при этом является ещё и "строковым выражением", то позволяет легко
+строить конкатенации с его участием.

+
+## Основные объекты библиотеки
+Доступны при любом использовании:
+- `simple_str<K>` - самая простая строка (или кусок строки), иммутабельная, не владеющая, аналог `std::string_view`.
+- `simple_str_nt<K>` - то же самое, только заявляет, что заканчивается 0. Для работы со сторонними C-API.
+
+Доступны при использовании всей библиотеки:
+- `sstring<K>` - shared string, иммутабельная, владеющая, с разделяемым буфером символов, поддержка SSO.
+- `lstring<K, N>` - local string, мутабельная, владеющая, с задаваемым размером SSO буфера.
+
+При подключении только `strexpr.h` - типы `simple_str<K>` и `simple_str_nt<K>` не содержат методов для работы с UTF и Unicode.

+
+## Использование
+Библиотеку можно использовать частично, просто взяв файл `"include/simstr/strexpr.h"` и включив в свои исходники
+```cpp
+#include "include/simstr/strexpr.h"
+```
+Это подключит только строковые выражения и упрощённые реализации `simple_str` и `simple_str_nt`, без функций работы с UTF и Unicode.
+
+Полная же версия библиотеки `simstr` состоит из трёх заголовочных файлов и двух исходников.
+Можно подключать как CMake проект через `add_subdirectory` (библиотека `simstr`),
+можно просто включить файлы в свой проект. Для сборки также требуется [simdutf](https://github.com/simdutf/simdutf) (при использовании CMake
+скачивается автоматически).
+
+### Подключение через FetchContent
+```
+function(add_simstr)
+    set(SIMSTR_BUILD_TESTS OFF)
+    set(SIMSTR_BENCHMARKS OFF)
+    FetchContent_Declare(
+        simstr
+        GIT_REPOSITORY https://github.com/orefkov/simstr.git
+        GIT_SHALLOW TRUE
+        GIT_TAG tags/rel1.9.1# Укажите нужный релиз
+        FIND_PACKAGE_ARGS NAMES simstr 1.9.1
+    )
+    FetchContent_MakeAvailable(simstr)
+endfunction()
+
+add_simstr()
+
+target_link_libraries(<your target> PUBLIC simstr::simstr)
+```
+
+Библиотека также включена в [vcpkg](https://vcpkg.io), подключается как `orefkov-simstr`.
+
+Для работы `simstr` требуется компилятор стандарта не ниже С++20 - используются концепты и std::format.
+Работа проверялась под Windows на MSVC-19 и Clang-19, под Linux - на GCC-13 и Clang-21.
+Также проверялась работа в WASM, сборка в Emscripten 4.0.6, Clang-21.
+
+## Удобная отладка
+Вместе с библиотекой поставляются два файла, делающие просмотр simstr строковых объектов в отладчиках
+более удобным.\
+Более подробно описано [здесь](for_debug/readme_ru.md).
+
+## Где уже используется
+Также simstr используется в моих проектах:
+- [simjson](https://github.com/orefkov/simjson) - библиотека для простой работы с JSON с использованием строк simstr.
+- [simrex](https://github.com/orefkov/simrex) - обёртка для работы с регулярными выражениями [Oniguruma](https://github.com/kkos/oniguruma) с использованием строк simstr.
+- [v8sqlite](https://github.com/orefkov/v8sqlite) - внешняя компонента для 1С-Предприятия V8 для работы с sqlite.
