The Unicode Standard defines a codespace: a set of integers called code points and denoted as U+0000 through U+10FFFF. The first two characters are always "U+" to indicate the beginning of a code point. They are followed by the code point value in hexadecimal. At least 4 hexadecimal digits are shown, prepended with leading zeros as needed. WebAug 7, 2024 · UTF-8 uses 1, 2, 3 or 4 bytes to represent a unicode character.
