🔬 Unicode Character Inspector

Enter text to see each character broken down by Unicode codepoint, hex value and UTF-8 byte sequence. This is a separate tool from Convert to Unicode Escapes, which only produces \u-escaped output — this one shows the full breakdown per character.

Text

One row per code point, not per byte

The text is walked by code point, so an emoji made of a surrogate pair gets a single row here even though JavaScript's own length counts it as two. The last column shows how the character is stored in UTF-8:

Char	Codepoint	Decimal	UTF-8 bytes
e	U+0065	101	65
é	U+00E9	233	C3 A9
日	U+65E5	26085	E6 97 A5
😀	U+1F600	128512	F0 9F 98 80

The pattern is worth remembering: ASCII takes one byte, accented Latin and Cyrillic two, CJK three, emoji four. That is why a 280 character limit and a 280 byte limit are different promises.

What it is actually good for

Identifying a space that will not behave. U+0020 is an ordinary space, U+00A0 a no-break space out of Word, U+200B a zero-width space that no trim will remove.
Spotting decomposed accents. If é comes back as two rows, U+0065 followed by U+0301, your text is in the NFD form macOS often produces - which breaks exact-match search and sorting.
Taking an emoji apart. Family emoji appear as several code points joined by U+200D, skin tones as a modifier in the U+1F3FB range.
Telling dashes apart before one breaks a CSV import: hyphen U+002D, en dash U+2013, em dash U+2014, minus sign U+2212.

The field holds one line and every character produces a row, so inspect the fragment you are chasing rather than a whole document. There is no character-name column - the codepoint is the key to look the name up with.

Frequently asked questions

How do I find the Unicode codepoint for a character?

Paste the character into the box and read the Codepoint column. The U+ form is what you want for CSS content, regex ranges and documentation; the decimal is what an HTML numeric entity uses.

Why does one emoji show up as three or four rows?

Because it is a sequence, not a character. A profession or family emoji is several pictographs stitched together with zero-width joiners, and each of those joiners is a code point in its own right.

Why is my accented letter listed as two characters?

It is stored as a base letter plus a combining mark rather than one precomposed code point. Both look identical on screen, but only one matches when you search.
