What is Invisible Character Detector?

The Invisible Character Detector scans your text for hidden Unicode characters like zero-width spaces, soft hyphens, and non-breaking spaces that can cause bugs in code, break copy-paste operations, or hide malicious content. Paste any text to instantly reveal every invisible character with its Unicode name and position.

How to use

1. Paste or type your text into the input area — hidden characters are detected instantly as you type.
2. Review the highlighted results showing each invisible character's Unicode name (e.g., U+200B Zero Width Space), position, and context.
3. Click 'Clean Text' to remove all invisible characters and copy the cleaned version to your clipboard.

Result

You paste a code snippet copied from a website that keeps throwing a syntax error. The detector reveals two zero-width spaces (U+200B) hidden between variable names, plus a right-to-left mark (U+200F) at the end of a line — all invisible in your editor but breaking your compiler.
