- character encoding — (character) (Or "character encoding scheme") A mapping between binary data values and character code positions (or "code points"). Early systems stored characters in a variety of ways, e.g. four six-bit characters in a 24-bit word, but around 1960, eight-bit bytes started to become the most common data storage layout, with each character stored in one byte, typically in the ASCII character set. In the case of ASCII, the character encoding is an identity mapping: code position 65 maps to the byte value 65. This is possible because ASCII uses only code positions representable as single bytes, i.e., values between 0 and 255. (US-ASCII only uses values 0 to 127, in fact.) From the late 1990s, there was increased use of larger character sets such as Unicode and many CJK coded character sets. These can represent characters from many languages and more symbols.
