Code page 437 is the
character set of the original
IBM PC (personal computer), or
MS-DOS. It is also known as CP437, OEM 437, PC-8, or MS-DOS Latin US. The set includes
ASCII codes 32–126, extended codes for accented letters (
diacritics), some Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "
extended ASCII" (one of many mutually incompatible ASCII extensions).
