Codepage is the traditional IBM term used for a specific character encoding table: a mapping in which a sequence of bits, usually a single octet representing integer values 0 through 255, is associated with a specific character.
Although IBM created and maintained many codepages, the term came to be associated primarily with character maps used by the IBM PC and compatible platforms, especially prior to the advent of Unicode-capable programming languages and operating systems.
The most notable of these is the windows-1252 codepage, which contains a range of typographical punctuation characters, the euro sign, and a few other special characters, in character positions which were reserved for control characters in the ISO 8859-1 "latin-1" codepage.
