# Modern C++20 Unicode Library
The goal of this library is to bring painless unicode support to C++ with simple and easy to understand APIs.
The API naming conventions are chosen to look familiar to those using the C++ standard libary.
### Feature Overview
- [x] API for accessing UCD properties
- [x] UTF8 <-> UTF32 conversion
- [x] wcwidth equivalent (`int unicode::width(char32_t)`)
- [x] grapheme segmentation (UTS algorithm)
- [x] symbol/emoji segmentation (UTS algorithm)
- [x] script segmentation [UTS 24](https://unicode.org/reports/tr24/)
- [x] unit tests for most parts (wcwidth / segmentation)
- [x] generic text run segmentation (top level segmentation API suitable for text shaping implementations)
- [ ] word segmentation (UTS algorithm)
- [x] CLI tool: `uc-inspect` for inspecting input files by code point properties, grapheme cluster, word, script, ...
# Unicode Technical Specifications
- [UTS 11](https://unicode.org/reports/tr11/) - character width
- [UTS 24](https://unicode.org/reports/tr24/) - script property
- [UTS 29](https://unicode.org/reports/tr29/) - text segmentation (grapheme cluster, word boundary)
- [UTS 51](https://unicode.org/reports/tr51/) - Emoji
### Integrate with your CMake project
```sh
git submodule add --name libunicode https://github.com/contour-terminal/libunicode 3rdparty/libunicode
```
```cmake
add_subdirectory(3rdparty/libunicode)
add_executable(your_tool your_tool.cpp)
target_link_libraries(your_tool PRIVATE unicode::unicode)
```

### Users of this library
* [Contour Terminal Emulator](https://github.com/contour-terminal/contour/)
### Disclaimer
This library is -in terms of features- by no means competive to the ICU library, but it attempts to
provide a clean and intuitive modern C++ API for those that do not want to fight legacy-style C APIs.
I hope that over time we can add more and more features to this library to conform to the Unicode
specification eventually at some point and I welcome everyone to contribute to it by forking the
library, creating pull requests, or even just constructive feedback.
