disarm

https://github.com/raeq/disarm

Ruby bindings for the disarm Rust core: TR39 confusable folding, bidi/zalgo/ zero-width neutralization, Unicode normalization, standards-based transliteration, slugification, and IDN/hostname spoof detection. The native extension wraps the pure-Rust core (no Python), so precompiled platform gems run without a local Rust toolchain.
