Why are code points and UTF-16 units different?

Characters above U+FFFF, such as most emoji, are stored as two UTF-16 units (a surrogate pair) but count as one Unicode code point. The summary shows both so you can see where strings will behave unexpectedly.

How are invisible characters shown?

Spaces, tabs, line feeds, and carriage returns get a visible label, and control characters are shown with a placeholder glyph, so you can spot hidden characters that cause bugs.

Is my text uploaded anywhere?

No. The inspection runs entirely in your browser and your text never leaves your device.

Unicode Character Inspector

Inspect every character in your text

This tool splits text into its individual Unicode code points and shows the U+ hex value, decimal value, and category (letter, number, symbol, punctuation, mark, control, and more) for each one.

It is built for debugging — spotting a stray non-breaking space, an invisible zero-width character, or a surrogate-pair emoji that is messing up your string lengths. The summary contrasts code points with UTF-16 units so the difference is obvious. Everything runs in your browser; nothing is uploaded.
