Clean hidden Unicode, zero-width spaces and smart quotes from text copied out of Word, Google Docs, or ChatGPT. Nothing legitimate gets touched — you control exactly what's removed.
Cleanup categories
ZWSP, ZWNJ, ZWJ, word joiner, BOM — invisible characters often left by AI tools or Word.
Converts curly quotes “ ” ‘ ’ into standard " and '.
Converts — and – into a plain hyphen -.
Converts non-breaking spaces (U+00A0) and other odd spacing characters to a regular space.
Removes non-printable control characters that can break scripts or downstream tools.
Removes trailing spaces/tabs at the end of each line.
Invisible characters pasted into code editors can cause silent syntax errors that are nearly impossible to spot visually.
Some AI-detection tools flag unusual Unicode patterns left by AI writing assistants — cleaning removes false-positive triggers.
Smart quotes and non-breaking spaces from Word often display as garbled symbols when pasted into web forms or CMSs.
Hidden characters between words can make search-and-replace or exact string matching silently fail.
