About JuliaStrings/utf8proc
utf8proc is a small, clean C library that provides Unicode normalization, case-folding, and other operations for data in the UTF-8 encoding. It supports Unicode version 17.0.0 and is used for basic Unicode support in the Julia language. Licensed under the MIT/expat license, it is regularly updated to keep up with recent Unicode releases. Originally developed by Jan Behrens and the Public Software Group, it is now maintained by the Julia developers. The library compiles easily with make or cmake and includes wrappers for Ruby, Rust, and Swift.
