What this tool does
Zero-width spaces and bidirectional-override characters render as nothing at all, which is exactly why they turn up in copy-paste tricks, spoofed filenames and text that looks identical but does not match in a diff or search. This tool lists every one it finds by position and code point, then offers a cleaned copy with those characters removed and unusual space separators normalized to a plain space.
How to use it
- Paste or type the text you want to check.
- Review the list of hidden characters, if any were found.
- Copy the cleaned text once you are ready.
Privacy
This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.
Frequently asked questions
- What counts as a hidden character?
- Zero-width spaces and joiners, bidirectional-override and embedding characters, unusual Unicode space separators such as the non-breaking space, and other control characters that render as nothing or as a plain-looking space.
- Does cleaning change normal spaces or punctuation?
- No. Only the specific hidden and unusual characters listed are removed or normalized; regular letters, numbers, spaces and punctuation are left as they are.
- Is the text I paste sent anywhere?
- No. Everything runs in your browser; nothing is uploaded or logged.
