About this tool
See every character of a text with its code point, UTF-8 and UTF-16 bytes, HTML entity and type, and spot what breaks code: invisible characters, unusual spaces and look-alike letters from other scripts. Clean up with one click – remove invisible characters, normalize spaces, turn smart quotes into ASCII, apply NFC or NFKC or strip accents.
Runs entirely in your browser – nothing you enter leaves this page.
