character encoding
(Or "character encoding scheme") A mapping of binary values to code pOSitions and back generally a 1:1 (bijective) mapping. In the case of ASCII, this is generally a f(x)=x mapping: code point 65 maps to the byte value 65, and vice versa. This is pOSsible because ASCII uses only code pOSitions representable as single bytes, i.e., values between 0 and 255, at mOSt. (US-ASCII only uses values 0 to 127, in fact.) Unicode and many CJK coded character sets use many more than 255 pOSitions, requiring more complex mappings: sometimes the characters are mapped onto pairs of bytes (see DBCS). In many cases, this breaks programs that assume a one-to-one mapping of bytes to characters, and so, for example, treat any occurrance of the byte value 13 as a carriage return. To avoid this problem, character encodings such as UTF-8 were devised.
