Code page 915
Code page 915 is a code page used under IBM AIX and DOS to write the Bulgarian, Belarusian, Russian, Serbian and Macedonian languages, but was never widely used. It would also have been usable for Ukrainian in the Soviet Union from 1933 to 1990, but it is missing the Ukrainian letter ge, ґ, which is required in Ukrainian orthography before and since, and during that period outside Soviet Ukraine. As a result, IBM created Code [page 1124]. It is an extension of ISO/IEC 8859-5. Code page 915 matches ISO/IEC 8859-5 directly from 0xA0 through 0xFF.
