A simple wrapper around [utf8proc](https://github.com/JuliaLang/utf8proc) for normalizing Unicode strings. Requires the `utf8proc` library and headers to be installed on your system. *(Packages are available. OSX: `brew install utf8proc`, Linux: `libutf8proc-dev` or `utf8proc-devel`)*
Currently supports UTF-8/ASCII string input and NFC, NFD, NFKC, NFKD, and NKFC-Casefold forms. Handles Unicode 9.0 and includes the current official full suite of 9.0 normalization tests.
Quick benchmarks against the [UNF](https://github.com/knu/ruby-unf) gem show it to be between the same speed (best-case) and ~2x slower (worst-case), averaging about ~1.2x slower on complex Unicode strings. The speed difference is more equal in NFC/NFD modes where mostly or already-normalized strings are used.
