Code page 437 (CCSID 437) is the character set of the original IBM PC (personal computer).[2] It is also known as CP437, OEM-US, OEM 437,[3] PC-8,[4] or DOS Latin US.[5] The set includes all printable ASCII characters as well as some accented letters (diacritics), Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "extended ASCII"[4] (one of many mutually incompatible ASCII extensions).

This character set remains the primary set in the core of any EGA and VGA-compatible graphics card. As such, text shown when a PC reboots, before fonts can be loaded and rendered, is typically rendered using this character set.[note 1] Many file formats developed at the time of the IBM PC are based on code page 437 as well.
