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. (1998-10-18)
