What it does
Normalize text using NFC, NFD, NFKC, or NFKD — the four standard Unicode normalization forms. Use NFC (the web default) to unify combining characters into precomposed forms, NFKC to also collapse compatibility characters (fi → fi, ① → 1). Great for fixing copy-paste weirdness, broken accents, and search mismatches.
