From Just Solve the File Format Problem
Code Page 855 (CP855, DOS 855, DOS CP855, DOS Cyrillic) is an 8-bit character encoding. It is a member of the family of MS-DOS encodings intended for use with languages using the Cyrillic alphabet. It got more use in Serbia, Macedonia and Bulgaria than in Russia, where CP866 was more popular. The lower half is the same as CP437 (and ASCII). CP872 is a variant with the euro sign in place of the generic currency sign.
