Unicode is the agreement that lets a Greek letter look the same in a French textbook, a Japanese website, and a Brazilian government form. Every character — every letter, digit, punctuation mark, symbol, and emoji you can type or read on a screen — has a number assigned to it. That number is its codepoint.

This site is a working reference for those characters. Each page documents one character, one block, or one technique, with the kind of detail you actually need: the codepoint in decimal and hex, the official name, the script and category, the HTML and CSS escapes, the UTF-8 and UTF-16 byte sequences, related characters, and notes on usage and history. No fluff. No pop-ups. Just the reference.
