# Unicode code point (`unicode_code_point`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Number of a character in Unicode, written in the notation of the Unicode Standard: U+ and four to six uppercase hexadecimal digits, with leading zeros only up to four digits, in the range U+0000 to U+10FFFF. Wikidata property P4213 and Unicode tables write the digits without the U+ prefix; the regexp requires it, because four bare hexadecimal digits look like any number. Lowercase forms such as u+00e9 occur in data but are not the standard notation.

## Detection

Regular expression (Python `re`):

```
^U\+(?:[0-9A-F]{4}|[1-9A-F][0-9A-F]{4}|10[0-9A-F]{4})$
```

## Examples

- `U+0041` — LATIN CAPITAL LETTER A
- `U+20AC` — EURO SIGN
- `U+1F600` — GRINNING FACE
- `U+41` (invalid example) — Fewer than four digits
- `U+110000` (invalid example) — Beyond the last code point U+10FFFF

## Mappings
