How many bytes are in unicode

WebEight bits are called a byte . One byte character sets can contain 256 characters. The current standard, though, is Unicode which uses two bytes to represent all characters in all writing systems in the world in a single set. The original ASCII was a 7 bit character set (128 possible characters) with no accented letters. 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.
