What is Unicode Code Point Lookup?
Unicode Lookup decomposes characters into their full description: Unicode codepoint (U+XXXX), decimal value, HTML numeric entity, UTF-8 byte sequence in hex, UTF-16 code units (with surrogate pair detection for supplementary plane), and JavaScript-compatible escape sequence (`\uXXXX` or `\u{XXXXX}` for ES2015+). In codepoint mode, enter `U+XXXX`, `0xXXXX`, or decimal to retrieve the character. This tool is part of santekno's developer toolbox — a curated collection of utilities built for engineers who care about speed, privacy, and simplicity.
Common use cases
- Debugging API payloads and integration issues
- Inspecting tokens, hashes, or encoded strings during development
- Generating fixtures and sample data for tests
- Sharing readable output with teammates in code reviews
FAQ
A code point is the abstract integer assigned to a character (U+1F389 = 🎉). A code unit is the storage unit of an encoding (UTF-16 stores 🎉 as 2 surrogate code units `D83C DF89`).
Each emoji codepoint above U+FFFF gets a single entry with both its full codepoint and its UTF-16 surrogate pair shown.
It is 4 codepoints: c, a, f, é. The "é" may also appear as 2 codepoints (e + combining acute) if NFD-decomposed — paste both forms to see the difference.
Standard Unicode notation. 4 hex digits for the Basic Multilingual Plane (≤U+FFFF), 5 for supplementary planes (e.g., U+1F389).
Up to 1000 characters per request (to keep output rendering snappy). The 1MB platform limit also applies.
