"ECMA-113" redirects here. For the encoding defined by the first (1986) edition of that standard, see ISO-IR-111.
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, RFC 1345 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 Windows-1251).
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 was a director of, prior to the founding of Evertype in 2001), and changes several of the non-Russian letters in order to support the Kildin Sami, Komi and Nenets languages, not supported by ISO-8859-5 itself. Michael Everson also introduced Mac OS Barents Cyrillic for the same languages on classic Mac OS.
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 republics of Russia.
