Remove Invisible Characters from Text

Questions
Remove Invisible Characters FAQ
Which invisible characters are removed?
The tool targets zero-width spaces and joiners, word joiners, byte order marks, and soft hyphens.
Will it remove normal spaces?
No. Normal spaces are preserved. Non-breaking spaces can be converted into ordinary spaces.
Can this detect AI-written text?
No. Hidden-character cleanup does not determine whether text was written by AI or a person.
