About Invisible Character Checker
An invisible character detection tool that scans text for hidden Unicode characters that are invisible to the naked eye but can cause bugs, security issues, and formatting problems. Detects zero-width spaces (U+200B), zero-width joiners (U+200D), non-breaking spaces (U+00A0), right-to-left marks (U+200F), soft hyphens (U+00AD), byte order marks (U+FEFF), and dozens of other control and formatting characters. Highlights their exact positions, shows Unicode code points, and offers one-click removal. Essential for developers debugging copy-paste issues, content moderators checking for homograph attacks, and writers cleaning up text.
