How this service works
Unicode character lookup by code point or character: name, block, category, UTF-8/UTF-16 bytes and HTML/JS/CSS escapes.
Output
Returns a structured object with the character's official Unicode name, code point, block, plane and plane name, general category code and full name, UTF-8/UTF-16/UTF-32 byte representations, UTF-16 unit count, HTML hex and decimal escapes, JavaScript escape (including surrogate pair for supplementary characters), CSS escape, URL-encoded form, Unicode version, scalar value and noncharacter flags, a validity verdict with reasons, data source and coverage notes, and a human-readable summary.
Example use cases
Emoji encoding for web output
“I need to know the UTF-8 byte sequence, HTML hex escape, and JavaScript escape for the 😀 emoji — can you look up U+1F600 for me?”
Identifying an unfamiliar symbol
“I found this character '€' in some text and I'm not sure what it is — can you look up its Unicode name, block, category, and all the encoding forms for it?”
CSS escape for special character
“What is the CSS escape sequence and URL-encoded form for the Unicode character at code point U+00A9 (the copyright sign)?”
Technical details
Endpoint
GEThttps://dev-reference.x402tookit.com/unicode-char?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, comprehensive Unicode metadata for a single code point — especially when you need encoding formats across multiple representations (UTF-8, UTF-16, HTML, JS, CSS) in one call. Prefer it over generic Unicode tables or character databases when an agent needs structured, machine-readable output with validity checking and escape sequences for web/code contexts.
Side effects
- Invalid or unrecognized code point format returns a non-valid verdict with reasons
- Code points outside the Unicode range may return nulls for most fields
- Surrogate code points flagged as non-scalar values
- Private-use or unassigned characters may have null name fields
- Malformed query parameter (missing cp) returns an error
