Character Helper

Character Helper is the definitive reference app for developers, designers, writers, and anyone who works with text. Whether you need to look up an ASCII control code, find the exact Unicode codepoint for a symbol, or browse emoji by category, Character Helper puts every character in the world's character sets right at your fingertips — completely offline.

COMPLETE ASCII TABLE
The full 128-character ASCII table is presented in a clean, searchable view. See every character alongside its decimal value, hexadecimal code, octal representation, binary form, and official name. Control characters include plain-English descriptions so you can instantly understand what each non-printable code means. Filter by category — printable, whitespace, control — or jump straight to the character you need.

UNICODE SEARCH
Search across the entire Unicode standard by character name, keyword, or symbol. Type "arrow" and see every arrow variant. Type "star" and discover a galaxy of star symbols from every writing tradition. Type the symbol itself to identify it instantly. Results show the codepoint, official Unicode name, block, and category, so you always know exactly what you're looking at.

BROWSE BY BLOCK
Explore Unicode the way it's organized — by block and script. Browse Latin, Greek, Cyrillic, Arabic, Devanagari, CJK, and hundreds of other blocks. Scroll through emoji groups, mathematical operators, box-drawing characters, currency symbols, and more. Discovering new characters is as satisfying as finding exactly the one you needed.

BOOKMARKS
Save the characters you use most. Your bookmarks are stored locally and load instantly — no account, no cloud sync needed. Whether you're keeping a list of arrow variants for a design project, mathematical symbols for a document, or special punctuation for your writing style, bookmarks make every repeat lookup instant.

TAP TO COPY
Every character is a single tap away from your clipboard. Copy the character itself, its UTF-8 escape sequence, or its HTML entity. Paste directly into your code, document, design tool, or message. Character Helper gets out of your way and puts the character in your clipboard as fast as possible.

FULLY OFFLINE
No internet connection required. The entire ASCII table and Unicode database live on your device. Use Character Helper in the subway, on a plane, at a conference with no Wi-Fi — the full reference is always available.

DESIGNED FOR DARK MODE
Character Helper uses a clean, dark-first design that is easy on the eyes during long reference sessions. Every character, value, and description is presented with crisp contrast and generous spacing for fast scanning.
