   Project mention: fd: A simple, fast and user-friendly alternative to 'find' | news.ycombinator.com | 2025-03-19

   Yes. I'm the one who implemented the case folding the `fd` uses (via its regex engine).

   See: https://github.com/rust-lang/regex/blob/master/UNICODE.md#rl...

   And then Unicode itself for more discussion on the topic: https://unicode.org/reports/tr18/#Simple_Loose_Matches

   TR18 used to have a Level 3[1] with the kind of locale-specific custom tailoring support found in GNU's implementation of POSIX locales, but it was so fraught that it was retracted completely some years ago.
