-## UTF-8 String For C++ (utf8::ustring)
+## ⚙️ UTF-8 String For C++ (utf8::ustring)
 
-## Brief Description:
-This is an implementation of the UTF-8 encoding standard for C++, the implementation is based on the std::basic_string\<char\> class, this gives us the advantage of std::basic_string\<char\> class functions, as well as compatibility with some functions from the standard library.
+## 📜 Brief Description:
+This is an implementation of the `UTF-8` encoding standard for `C++`, the implementation is based on the `std::basic_string<char>` class, this gives us the advantage of `std::basic_string<char>` class functions, as well as compatibility with some functions from the standard library.
 
-## Code Style:
-- C++ AStyle code style was used for this project.
+## 📝 Code Style:
+- `C++ AStyle` code style was used for this project.
 
-## Technical Dependencies:
-- C++ 20
-- CMake 3.14
+## 🛠 Technical Dependencies:
+- `C++ 20`
+- `CMake 3.14`
 
-## Support Status On Systems:
-- [X] Linux
-- [ ] Windows (not yet verified)
+## 🔗 Support Status On Systems:
+- [X] Linux (verified on clang)
+- [X] Windows (verified on gcc && clang)
 
-## Library Features:
+## 💫 Library Features:
 - Support for creating an object from: `std::string, std::string_view, const char*`
 - Comparing an `utf8::ustring` with `utf8::ustring` (comparison with `const char*`, `std::string`, `std::string_view` will be added in the future)
 - Copy/Move (<- assignment also) constructor implemented 
 - O(1) Random Access
-- Simple replacement of any character, e.g. a smaller character (1 byte) with a larger character (2-3-4 bytes).
+- Simple replacement of any character, e.g. a smaller character `(1 byte)` with a larger character `(2-3-4 bytes)`.
 
-## Performance Test:
+## ⚡️ Performance Test:
 | String-Version |        Test-Name        | iteration count | time (for all iterations) | 
 |:--------------:|:-----------------------:|:---------------:|:-------------------------:|
 |  std::string   |      replace_char       |     500'000     |          ~0.57s           |                          
 | utf8::ustring  |      replace_char       |     500'000     |          ~0.60s           |
 
-## Coming Soon:
-- A more detailed test and description of the string speed.
-- Test in Windows.
-- Introduction of new functions.
-- Code samples.
+## ❔ Replace Char O(1) ?
+Yes and no, in the case where we replace a character with another `with the same size`, we have `O(1)`, in the other case we have `O(~N)`, where N is the length of the string.
+But in any case we have `O(1) Random Access`.

+## 📚 Code Samples:
+```cpp
+std::string str{ "hello world!" };
+utf8::ustring ustr{ str };
+
+ustr.replace_char("п", 0); // "пello world!"
+
+ustr == "hi !"; // false
+ustr == str; // false
+```
+
+## ⭐️ Coming Soon:
+- Write/read to file.
+- Add new features.
+- Docs.
