Unicode Normalization C++ Source Code Reference

Question

I want to implement Unicode Normalization in C++, specially NFKC. To do so I need some reference source code in any language(prefarable C++).

Or you may suggest me how can I start my implementation.

Answer 1

You're in luck, because a regular at the Lounge<C++> here at SO.com is writing a complete Unicode implementation in C++. It is meant as a full replacement of ICU, without any of its drawbacks:

It doesn't currently implement NFKC, but NFC and NFD are implemented, and could be used as "some reference source code".
