MacCyrillic
From Just Solve the File Format Problem
MacCyrillic (Mac OS Cyrillic) is a character encoding used on classic Mac OS, for the Cyrillic alphabet. The original version lacked one of the characters used in Ukrainian, and a variant version called MacUkrainian added that, but then this was merged into a later version of MacCyrillic at the same time the euro symbol was added.
See Macintosh encodings for related encodings.
