What it does
See exactly which characters a piece of text contains: each one is listed with its Unicode code point, UTF-8 bytes and HTML entity. A Cyrillic а in a domain shows up as U+0430 instead of U+0061.
It runs entirely in your browser: nothing you enter is uploaded.
Example
Lookalike domain
exаmple.comexаmple.comThe third row shows U+0430 with two UTF-8 bytes (0xD0 0xB0): a Cyrillic а, not the Latin a (U+0061) of example.com.
FAQ
What does each row show?
The character, its code point in U+ notation and as hex, its UTF-8 bytes and a decimal HTML entity. The text is split by code point, so an emoji such as U+1F600 takes one row while a letter with a combining accent takes two.
Does it flag lookalike or invisible characters?
No. It lists every code point without names or warnings, so look for values outside the range you expect, such as U+0400 to U+04FF (Cyrillic) in a Latin domain; zero-width characters appear as rows with an empty-looking Char cell. The Homoglyph Checker and the Invisible Character Detector flag these automatically.
Is the text sent anywhere?
No. The table is built in your browser as you type, and nothing is uploaded.
