How to use / Notes

How to use

  1. Paste text to detect whitespace, zero-width characters, and direction controls.
  2. Use the visualized preview, Unicode code points, and JavaScript notation to find each occurrence.
  3. Copy or apply the text without detected characters when appropriate. The catalog copies the actual character.

Notes

  • Some invisible characters are required for joining, language shaping, emoji, or text direction. Check their purpose before removing them.
  • U+200D (zero-width joiner) is used in emoji sequences. Do not remove U+200C or direction controls indiscriminately.
  • Input is processed in the browser and is not sent anywhere.
