How Unicode Inspector & Invisible Character Finder works

Each character is listed with its code point, name for the tricky ones, category, script and its UTF-8 and UTF-16 bytes. Hidden characters such as zero-width spaces, direction overrides and soft hyphens are highlighted, and Cyrillic or Greek letters that look like Latin ones are flagged. One click removes or replaces them.

Input: Text. Output: Text.
