Computer Programming Software Terms, Glossary and Dictionary
Character mapping refers to the process of using a table used in an operating system or font to map the character codes to the glyphs used in a font. Most character encoding uses an 8-bit system allowing a maximum of 256 character codes. Extended or non-AlphaNumeric languages often use 16-bit or Double Byte encoding. Also, Character Maps or not necessarily cross platform compatible. For example, the Macintosh and Windows operating systems use differing character maps. However, Type 1 fonts do contain the glyphs necessary for both these mappings and so work in both Macintosh and Windows systems and others.
