MIK (МИК) is an 8-bit Cyrillic code page used with DOS. It is based on the character set used in the Bulgarian Pravetz 16 IBM PC compatible system. Kermit calls this character set "BULGARIA-PC" / "bulgaria-pc". In Bulgaria, it was sometimes incorrectly referred to as code page 856 (which clashes with IBM's definition for a Hebrew code page). This code page is known by Star printers and FreeDOS as Code page 3021 (Earlier it was known by FreeDOS as code page 30033 (now used for a code page 857 variant which contains the Crimean Tatar hryvnia sign), but it was renumbered to match the Star Printer code page).
This is the most widespread DOS/OEM code page used in Bulgaria, rather than CP 808, CP 855, CP 866 or CP 872.
Almost every DOS program created in Bulgaria, which has Bulgarian strings in it, was using MIK as encoding, and many such programs are still in use.
