ISO-IR-111

ISO-IR-111[1] or KOI8-E[2] (formerly also ECMA-113 (1st ed., 1986)[3]) is an 8-bit character set. It is a multinational extension of KOI-8 for Belarusian, Macedonian, Serbian, and Ukrainian (except Ґґ which is added to KOI8-F).

Naming confusion
Further information: ISO-IR-153 § Standards

ISO-IR-111, the 1985 edition of ECMA-113 (also called "ECMA-Cyrillic" or "KOI8-E"), was based on the 1974 edition of GOST 19768 (i.e. KOI-8). In 1987 ECMA-113 was redesigned.[4] These newer editions of ECMA-113 are equivalent to ISO-8859-5,[4] [5] and do not follow the KOI layout. This confusion has led to a common misconception that ISO-8859-5 was defined in or based on GOST 19768-74.[5]

Possibly as another consequence of this, RFC 1345 erroneously lists a different codepage under the names "ISO-IR-111" and "ECMA-Cyrillic", resembling ISO-8859-5 with re-ordered rows, and partially compatible with Windows-1251.[6][5]

Incorrect RFC 1345 code page
RFC 1345's "ECMA-Cyrillic"
Language(s)Russian, Belarusian, Macedonian, Serbian
StandardRFC 1345
ClassificationExtended ASCII
Transforms / EncodesISO-IR-111
Other related encoding(s)ISO-8859-5, Windows-1251

RFC 1345 erroneously lists a different codepage under the name ISO-IR-111, encoding the same Cyrillic characters but with a different layout. It resembles a mixture of Windows-1251 and ISO-8859-5.[6] Specifically, line A_ corresponds to ISO-8859-5, lines C_ through F_ correspond to Windows-1251[5] (equivalent to lines B_ through E_ of ISO-8859-5), and line B_ nearly corresponds to line F_ of ISO-8859-5, with the exception of the § being replaced with a ¤.

Certain codes resemble ISO-IR-111 with flipped letter case, which may have contributed to the confusion. The majority differ and are shown below with a heavy border.
