Editing Code page (section)

=== DOS code pages ===
These code pages are used by IBM in its [[PC DOS]] operating system. These code pages were originally embedded directly in the [[text mode]] hardware of the graphic adapters used with the [[IBM PC]] and its clones, including the original MDA and CGA adapters whose character sets could only be changed by physically replacing a ROM chip that contained the font.  The interface of those adapters (emulated by all later adapters such as VGA) was typically limited to single byte character sets with only 256 characters in each font/encoding (although VGA added partial support for slightly larger character sets).

When dealing with older hardware, protocols and file formats, it is often necessary to support these code pages, but newer encoding systems, in particular Unicode, are encouraged for new designs.

DOS code pages are typically stored in .CPI files.<ref name="Paul_2001_CPI"/><ref name="Elliott_2006_CPI"/><ref name="AEB_2001_CPI"/><ref name="Haralambous_2007_CPI"/><ref name="MS_1991_PR"/>
