Unicode Code Point Viewer

A Unicode code point is a unique number assigned to every character in the Unicode standard. Each code point is written as U+ followed by a hexadecimal number (e.g., U+0041 for the Latin letter A, U+4E00 for the CJK ideograph 一, or U+1F600 for the grinning face emoji 😀). The Unicode standard defines over 149,000 characters across 161 scripts and hundreds of blocks, making it the universal character encoding system used by virtually all modern software and the web. Our Unicode code point viewer lets you explore every character in any text, showing its code point, official name, category, block, and byte-level encodings.

1. 1. Enter or paste text: Type or paste any text into the input area. The tool instantly analyzes every character and displays detailed Unicode information for each code point in a sortable table. Characters are iterated by Unicode code point, not by visible grapheme clusters.
2. 2. Review summary statistics: The summary cards show total code points, letter/digit/punctuation/symbol counts, and total byte sizes for UTF-8 and UTF-16 encodings. The category and block distribution charts help you understand the composition of your text at a glance.
3. 3. Filter, search, and explore: Use the search box to find specific characters by name or code point. Filter by Unicode category (Lu for uppercase, Nd for digits, etc.) or by Unicode block. Click any row to expand detailed information including UTF-8/UTF-16 byte sequences, HTML entities, and JSON escape sequences - all copyable for use in your projects.

• Code Points vs. Code Units: A code point (U+0041) is the abstract character identifier. Code units are the actual byte sequences used to store or transmit the character - UTF-8 uses 1-4 bytes per code point, while UTF-16 uses 1-2 16-bit units (2-4 bytes). Characters above U+FFFF require two UTF-16 code units, known as a surrogate pair.
• Unicode Categories: Every code point belongs to a general category identified by a two-letter code: Lu (Uppercase Letter), Ll (Lowercase Letter), Nd (Decimal Number), Po (Other Punctuation), Sm (Math Symbol), Sc (Currency Symbol), and many more. The first letter indicates the major class: L (Letter), N (Number), P (Punctuation), S (Symbol), Z (Separator), C (Control), M (Mark).
• Unicode Blocks: Characters are organized into contiguous ranges called blocks, each covering a script or category - Basic Latin, Cyrillic, CJK Unified Ideographs, Emoticons, Mathematical Operators, and over 250 others. Each block has a name and a defined range of code points.
• UTF-8 and UTF-16 Encoding: UTF-8 is the dominant encoding on the web, using variable-length byte sequences (1-4 bytes per code point) that are backward-compatible with ASCII. UTF-16 uses 2 or 4 bytes per code point and is used by JavaScript strings and many system APIs. The tool shows both encodings for every character so you can see the difference.

While our Unicode code point viewer provides comprehensive analysis of individual code points, there are important concepts to understand. Code points are not the same as visible characters - a single visible grapheme cluster can consist of multiple code points (e.g., an base letter followed by combining diacritical marks, or an emoji followed by a variation selector). The tool analyzes code points individually, so combining character sequences are shown as separate entries. Characters outside the Basic Multilingual Plane (BMP), including most emoji and many CJK characters, usesurrogate pairs in UTF-16, which are shown as two code units. The character name database covers common ASCII, Latin-1 Supplement, and popular Unicode characters - characters beyond this range show their code point as a fallback name. All analysis is performed entirely in your browser - no data is uploaded to any server.
