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.

• API for accessing UCD properties
• UTF8 <-> UTF32 conversion
• wcwidth equivalent (int unicode::width(char32_t))
• grapheme segmentation (UTS algorithm)
• symbol/emoji segmentation (UTS algorithm)
• script segmentation UTS 24
• unit tests for most parts (wcwidth / segmentation)
• generic text run segmentation (top level segmentation API suitable for text shaping implementations)
• word segmentation (UTS algorithm)
• CLI tool: uc-inspect for inspecting input files by code point properties, grapheme cluster, word, script, ...

• UTS 11 - character width
• UTS 24 - script property
• UTS 29 - text segmentation (grapheme cluster, word boundary)
• UTS 51 - Emoji

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.
