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.

How to use it

  1. Paste the text that looks odd.
  2. Pick a normalization form — NFC is the safe default.
  3. Read the before/after and the number of codepoints changed.
  4. Copy the normalized result.
