Unicode Character Lookup

Unicode Character Lookup - Find Code Points & Encodings Online

Inspect any character to see its Unicode code point, hexadecimal value, UTF-8 byte encoding, and HTML entity.

Type or paste any character into the input field and the tool displays its Unicode properties: official name, code point (U+XXXX), hexadecimal value, UTF-8 byte sequence, UTF-16 encoding, and HTML entity (both decimal &#N; and named &entity; if available). Properties also include the Unicode block (Latin, CJK, Emoji, etc.) and character category. For multi-character input, each character is analyzed separately. The lookup is instant and uses browser-native Unicode data.

Developers troubleshoot encoding issues by identifying which character caused UTF-8 decode errors in logs. Technical writers find HTML entities for special symbols like copyright ©, trademark ™, or currency symbols. Linguists analyze text samples to identify script systems and character sets. Security researchers detect homograph attacks by inspecting visually similar characters from different Unicode blocks (like Cyrillic o vs. Latin o).

Code points above U+FFFF require surrogate pairs in UTF-16—emoji and rare CJK characters fall into this range. HTML named entities exist only for common symbols; use decimal/hex entities for comprehensive coverage. UTF-8 byte length varies (1-4 bytes per character)—this matters for byte-based string length limits in databases or protocols. Zero-width characters (U+200B, U+FEFF) won't display visibly but affect text processing. Check the character category (Letter, Symbol, Punctuation) to understand why certain characters behave unexpectedly in regex or sorting.

All processing happens directly in your browser. Your files never leave your device — no server uploads, no cloud storage, no data retention. The tool works offline once loaded, requires no registration, and is completely free with no usage limits.
