Technical Details

How Diacritic Removal Works

Conversion process:

  1. Text is normalized to Unicode NFD form (decomposed characters)
  2. Diacritical marks are identified and filtered out
  3. Text is recomposed to standard NFC form
  4. Special cases are handled (e.g., German ß remains unchanged)

Common Diacritics Removed

  • Acute accents: á, é, í, ó, ú
  • Grave accents: à, è, ì, ò, ù

  • Tilde: ã, ñ, õ
  • Cedilla: ç
  • And many other combining diacritical marks
