How to find hidden characters in text
Hidden characters can be legitimate language controls, formatting marks, or accidental copy-and-paste residue. The reliable way to investigate them is to inspect the actual code points instead of trusting visual appearance.
What to look for
Zero-width spaces, directional controls, soft hyphens, joiners, and no-break spaces can change matching, line wrapping, and text direction. RevealText labels these code points and shows their exact positions before you remove anything.
Clean conservatively
Review every change. In particular, keep joiners when text uses scripts or emoji sequences that rely on them.
