Text cleanup

How to remove invisible characters from copied text

Invisible characters are formatting marks that take up little or no visible space. They can appear after copying from PDFs, websites, word processors, spreadsheets, and translated text. Common examples include zero-width spaces, soft hyphens, non-breaking spaces, byte order marks, and left-to-right or right-to-left marks.

Checklist

1. Paste the text into a hidden-character preview.
2. Look for markers around line breaks, pasted links, names, numbers, and code snippets.
3. Remove invisible marks that are not intentionally part of the text.
4. Replace non-breaking spaces with normal spaces when the destination editor does not need them.
5. Retest the cleaned text in the original form, editor, or import tool.

Warning signs

Hidden characters are likely when search fails to match visible words, pasted code throws unexpected errors, CSV columns shift, or a form rejects text that appears valid.

FAQ

Are invisible characters always bad? No. They can be legitimate in multilingual text and typography. Remove them only when they are causing problems or were accidentally copied.

Can I see them manually? Some code editors reveal whitespace, but browser cleanup tools are faster for everyday text.
