It is a variant of the original Mac OS Cyrillic encoding. Code points 162 (0xA2) representing the character ‹¢› and 182 (0xB6) representing the character ‹∂› were redefined to represent ‹Ґ› and ‹ґ›, respectively.
Since Mac OS 9, ‹Ґ› and ‹ґ› have been included in the Macintosh Cyrillic encoding. FreeDOS calls it code page 58627.[2]
