Invisible Unicode characters hide in copied text — zero-width spaces, byte-order marks, word joiners, directional marks. They break search, corrupt code, and can fingerprint where text came from.
CopyCleanse highlights every invisible character and shows its exact code point (like U+200B) when you hover over it, then removes them all in one click. Scan-only mode lets you inspect text without modifying it.

Frequently asked questions
How do I see invisible characters in my text?
Paste your text and run a scan: CopyCleanse highlights each invisible character and shows its exact code point when you hover over it, so you can see exactly what it is and where it sits.
Which invisible characters are removed?
Zero-width spaces and non-joiners, byte-order marks, word joiners, invisible math operators, bidirectional marks and isolates, soft hyphens, Mongolian vowel separators, Hangul fillers, tag characters, and variation selectors outside emoji.
Will it break my emoji?
No. Zero-width joiners and variation selectors that are part of legitimate emoji sequences are preserved.
