<p>Code page 437 (<a href="/facts/CCSID/NKSgxNDg">CCSID</a> 437) is the <a href="/facts/Character_set/ShJHIMoA">character set</a> of the original <a href="/facts/IBM_PC/yhcJGMPL">IBM PC</a> (personal computer). It is also known as CP437, OEM-US, OEM 437, PC-8, or MS-DOS Latin US. The set includes all printable <a href="/facts/ASCII/vGUI33Qu">ASCII</a> characters as well as some accented letters (<a href="/facts/Diacritic/Rw6lMzQW">diacritics</a>), Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "<a href="/facts/Extended_ASCII/Agfdo1R0">extended ASCII</a>" (one of many mutually incompatible ASCII extensions).
</p><p>This character set remains the primary set in the core of any <a href="/facts/Enhanced_Graphics_Adapter/VFU5QRyp">EGA</a> and <a href="/facts/Video_Graphics_Array/8GGsGTSc">VGA</a>-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. Many file formats developed at the time of the IBM PC are based on code page 437 as well.
