ISO-IR-111[1] or KOI8-E[2] 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). The name "ISO-IR-111" refers to its registration number in the ISO-IR registry, and denotes it as a set usable with ISO/IEC 2022.

It was defined by the first (1986) edition of ECMA-113,[3] which is the Ecma International standard corresponding to ISO/IEC 8859-5, and as such also corresponds to a 1987 draft version of ISO-8859-5.[4] The published editions of ISO/IEC 8859-5 instead correspond to subsequent editions of ECMA-113, which defines a different encoding.[5]

Naming confusion[edit]

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.[5] These newer editions of ECMA-113 are equivalent to ISO-8859-5,[5][6] 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.[6]

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.[7][6] Due to concerns that existing implementations might use the RFC 1345 definition for those two labels, it was proposed that the IANA additionally recognise KOI8-E as a label for ECMA-113:1985 content,[7] and the IANA presently lists that label as an alias.[2]

Extended and modified versions[edit]

A modified version named KOI8 Unified or KOI8-F was used in software produced by Fingertip Software, adding the Ґ in its KOI8-U location (replacing the soft hyphen and displacing the universal currency sign), and adding some graphical characters in the C1 control codes area, mainly from KOI8-R and Windows-1251.[4][6][8][9]

Incorrect RFC 1345 code page[edit]

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 code page 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.[7] Specifically, line A_ corresponds to ISO-8859-5, lines C_ through F_ correspond to Windows-1251[6] (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.

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
