What is Character Reference?

Character Reference is an all-in-one tool that combines ASCII table, Unicode lookup, and emoji picker. It helps you find character codes, look up Unicode information, and browse emojis all in one place.

How do I use the ASCII table?

Browse the complete ASCII table (0-127) with decimal, hexadecimal, octal, and binary representations. Search by code, character, or description. Click any value to copy it to your clipboard.

How do I lookup Unicode characters?

Enter a character in the input field to see its Unicode information, or search by code point (U+0041, 0x41, or 65), character name, category, or block. The tool displays code point, HTML entity, CSS escape, JavaScript escape, and UTF-8 bytes.

How do I use the emoji picker?

Browse emojis by category using the category tabs, or use the search box to find specific emojis. Click on any emoji to copy it to your clipboard. Recently used emojis appear at the top for quick access.
