How Unicode code points work

Every character in Unicode is assigned a unique integer called a code point. For example, the letter "A" is U+0041, the euro sign "€" is U+20AC, and the rocket emoji "🚀" is U+1F680. Code points are written in hexadecimal with a U+ prefix, but can also be expressed as decimals or as escape sequences like A (for BMP characters) or \u{1F680} (for characters above U+FFFF).

For per-character Unicode details, see Unicode Character Info. To escape JSON strings, try JSON Escape / Unescape.

What this tool is used for

Producing code points to identify an unexpected character precisely.
Building an escaped representation for a format that cannot carry the characters.
Checking whether two similar-looking strings are the same characters.
Producing a code point list for a bug report about encoding.
Confirming how many code points a visible character actually uses.

Frequently Asked Questions

What is the U+ notation?: The Unicode standard's own way of writing a code point: U+ followed by at least four hexadecimal digits, upper case. U+0041 is A. Four digits cover the Basic Multilingual Plane; anything above it, such as an emoji at U+1F600, takes five or six.
Is a code point the same as a character?: Not quite. An emoji with a skin tone is two code points, a flag is two, and a family emoji can be seven joined by U+200D. What a reader calls one character is a grapheme cluster, which is why the code-point count is usually higher than the visible length.
Which format should I choose?: U+XXXX for documentation and bug reports, `\uXXXX` for JavaScript, Java or JSON string literals, and decimal for HTML numeric entities. Note that `\u` in most languages takes exactly four digits — astral characters need `\u{1F600}` or a surrogate pair.
What is a surrogate pair?: How UTF-16 stores a code point above U+FFFF: two units in the D800–DFFF range that together encode one character. This tool reports the real code point rather than the pair, which is why an emoji shows as one U+1F600 and not as two mysterious D-values.
What is it good for?: Identifying the character that broke something. A pasted string with a non-breaking space (U+00A0), a smart quote (U+2019), a zero-width joiner (U+200D) or a right-to-left mark (U+200F) looks normal and behaves strangely — decoding it names the culprit exactly.
Why does one visible character produce several code points?: Because emoji sequences, accented letters written in decomposed form, and flags are all built from multiple code points. What looks like one character is a grapheme cluster, which is a different unit entirely.

Common errors and gotchas

Round-tripping a sequence and reassembling it in the wrong order, which changes the character.
Confusing a code point with its UTF-8 or UTF-16 bytes, which are different numbers.
Mixing hex and decimal without recording which, so the values are ambiguous.
Producing escapes in a syntax the target language does not use.
Splitting a surrogate pair and producing two invalid values instead of one character.
