Code page 915 (CCSID 915) (also known as CP 915, IBM 00915) is a code page used under IBM AIX and DOS to write the Bulgarian, Belarusian, Russian, Serbian and Macedonian but was never widely used. It would also have been usable for Ukrainian in the Soviet Union from 1933–1990, 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.
