It was designed to cover languages using a Cyrillic alphabet such as Bulgarian, Belarusian, Russian, Serbian and Macedonian but was never widely used.
The initial draft of ISO-8859-5 (DIS-8859-5:1987) followed ISO-IR-111, but was revised[4] after GOST 19768-74 was replaced[5] by the new ISO-IR-153 in 1987, which re-arranged the Russian letters into alphabetical order (except for Ё).
[5][6] 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.
ISO-IR-200, "Uralic Supplementary Cyrillic Set",[9] was registered in 1998 by Everson Gunn Teoranta (which Michael Everson was a director of, prior to the founding of Evertype in 2001),[10] 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.
[11] ISO-IR-201, "Volgaic Supplementary Cyrillic Set",[12] 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.
