ASCII and Unicode code points explained
Every character a computer displays maps to a number called a code point. The first 128 (0-127) are the classic ASCII set, covering English letters, digits and basic punctuation; Unicode extends this to cover every script and emoji in use today, up to over a million code points.
This tool shows a character’s code point in the formats programmers commonly need: decimal, hex (U+ notation), binary, and the HTML numeric entity.
