Code page

Code page 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. A few code pages use more than 8 bits per character and thus encode more than 256 characters. The term cmap (character map) is used in technical documentation on Macintosh platforms.

Although IBM created and maintained many code pages, 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.

To this day, it is typical for PC hardware to support a single 8-bit code page that is, by default, for a particular regional market, and to make available mechanisms for operating systems to switch to other code pages. However, it is now commonplace for operating system vendors to provide their own character encoding and rendering systems that bypass the hardware code pages entirely. These alternative character encodings are sometimes called code pages as well.

Character encoding: A character encoding consists of a code that pairs a set of characters (representations of graphemes or grapheme-like units, such as might appear in an alphabet or syllabary for the communication of a natural language) with a set of something else, such as numbers or electrical pulses, in order to f...
