History and related code pages

The ECMA-113 standard has been equivalent to ISO-8859-5 since its second edition, its first edition ( ISO-IR-111) having been an extension of the earlier KOI-8 (defined by GOST 19768-74), which lays out the Russian letters in the same way as their ASCII Roman equivalents where possible. The initial draft of ISO-8859-5 (DIS-8859-5:1987) followed ISO-IR-111, but was revised after GOST 19768-74 was replaced by the new ISO-IR-153 in 1987, which re-arranged the Russian letters into alphabetical order (except for Ё). ISO-IR-153 contains the Russian letters, including Ё, and the non-breaking space and soft hyphen, whereas the full Cyrillic set of ISO-8859-5 is also called ISO-IR-144. Possibly as a consequence of this confusion, erroneously lists yet another code page as "ISO-IR-111", combining the letter order and case order of ISO-8859-5 with the row order of ISO-IR-111 (and consequently compatible with neither in practice, but in practice partially compatible with

). IBM Code page 915 is an extension of ISO/IEC 8859-5, adding some semigraphic and other symbols in the C1 area. IBM Code page 1124 is mostly identical to ISO-8859-5, but replaces ѓ with ґ for Ukrainian use. ISO-IR-200, "Uralic Supplementary Cyrillic Set", was registered in 1998 by Everson Gunn Teoranta (which

Michael Everson also introduced Mac OS Barents Cyrillic for the same languages on classic Mac OS. FreeDOS calls it code page 59283. ISO-IR-201, "Volgaic Supplementary Cyrillic Set", was similarly introduced by Everson Gunn Teoranta in order to support the Chuvash, Komi, Mari and Udmurt languages, spoken in the titular
