'''KOI-7''' ('''КОИ-7''') is a 7-bit [[character encoding]], designed to cover [[Russian language|Russian]], which uses the [[Cyrillic]] alphabet.


In Russian, KOI7 stands for ''Kod Obmena Informatsiey, 7 bit'' (Код Обмена Информацией, 7 бит) which means "Code for Information Exchange, 7 bit".
In Russian, KOI-7 stands for ''Kod Obmena Informatsiey, 7 bit'' (Код Обмена Информацией, 7 бит) which means "Code for Information Exchange, 7 bit".<ref name="GOST-27463-87"/>


It was first standardized in GOST 13052-67 (with the 2nd revision GOST 13052-74 / ST [[Comecon|SEV]] 356-76) and GOST 27463-87 / ST SEV 356-86.

[[Shift Out]] (SO) and [[Shift In]] (SI) [[control characters]] are used in KOI-7, where SO starts printing [[Russian alphabet|Russian letters]] (KOI-7 N1), and SI starts printing [[Latin alphabet|Latin letters]] again (KOI-7 N0), or for [[lowercase]] and [[uppercase]] switching. This version is also known as '''KOI7-switched''' aka '''csKOI7switched'''.<ref name="Sokolov_2004_KOI7-switched"/><ref name="IANA_2013"/>
{| {{chset-tableformat}}

On [[ISO 2022]] compatible [[computer terminal]]s KOI7-switched can be activated by the escape sequence <code>ESC ( @ ESC ) N LS0</code>.<ref name="Sokolov_2004_KOI7-switched"/>

KOI-7 was used on machines like the [[SM EVM]] (СМ ЭВМ) and [[DVK]] (ДВК); KOI-7 N2 was utilized in the machine-language of the {{ill|Электроника Д3-28|ru}} (Elektronika D3-28) as four-digit hexadecimal code, {{ill|БЭСМ-6|ru}} (BESM-6), where it was called ВКД, (internal data code). The encodings were also used on [[RSX-11]], [[RT-11]] and similar systems.<ref name="Nechayev_2013_8-Bit-Cyrillic"/>

=={{anchor|N0}}KOI-7 N0==
'''KOI-7 N0'''<ref name="Sokolov_2004_KOI7-switched"/> ('''КОИ-7 Н0'''<ref name="GOST-27463-87"/>) is identical to the IRV set in [[ISO 646]]:1967.<ref name="Sokolov_2004_KOI7-switched"/> Compared to [[US-ASCII]], the [[dollar sign]] ("$") at code point 24 (<sub>hex</sub>) was replaced by the [[universal currency sign]] "¤", but this was not maintained in all cases, in particular not after the fall of the [[Iron Curtain]]. Likewise, the IRV set in [[ISO/IEC 646:1991]] also changed the character back to a dollar sign.

=={{anchor|N1}}KOI-7 N1==

'''KOI-7 N1''' ('''КОИ-7 Н1'''<ref name="GOST-27463-87"/>) was first standardized in GOST 13052-67,<ref name="Clews_1988"/><ref name="Czyborra_1998_Cyrillic"/><ref name="Hohlov"/> and later also in [[ISO 5427]].<ref name="Sokolov_2004_KOI7-switched"/> It is sometimes referred to as "koi-0" as well.<ref name="Czyborra_1998_Cyrillic"/>

Compared to [[ASCII]] and [[ISO/IEC 646|ISO 646]] uppercase and lowercase letters are swapped in order to make it easier to recognize Russian text when presented using ASCII.<ref name="Czyborra_1998_Cyrillic"/>

To trim the alphabet into chunks of 32 characters the dotted [[Ё]]/ë was dropped.<ref name="Czyborra_1998_Cyrillic"/> In order to avoid conflicts with ASCII's and ISO 646's definition as [[Delete character|DEL]] and its usage as [[end-of-file|EOF]] marker (-1) in some systems, it dropped the "CAPITAL HARD SIGN" [[Ъ]] that would have naturally resided at this location.<ref name="Czyborra_1998_Cyrillic"/>

In a Bulgarian variant the unnecessary Russian "CAPITAL YERY" [[Ы]] at code point 121 was replaced by the "CAPITAL HARD SIGN" Ъ.<ref name="Czyborra_1998_Cyrillic"/>

=={{anchor|N2}}KOI-7 N2==
The [[dollar sign]] character ("$" hex 24), however, was often replaced with the [[Currency (typography)|universal currency sign]] "¤" in Soviet computers. A popular legend has it that this was to demonstrate independence of the American-dominanted computer industry — which was ironical, since a significant number of Soviet computers were actually implementations of various American designs.

'''KOI-7 N2''' ('''КОИ-7 Н2'''<ref name="GOST-27463-87"/>), like KOI-7 N1, was also standardized in GOST 13052-67.<ref name="Hohlov"/>

[[Kermit (protocol)|Kermit]] names it '''SHORT-KOI''' / '''short-koi'''.<ref name="Cruz_2010_Kermit"/><ref name="Kermit_Short-KOI"/>

KOI-7 (КОИ-7) is a 7-bit character encoding, designed to cover Russian, which uses the Cyrillic alphabet.

In Russian, KOI-7 stands for Kod Obmena Informatsiey, 7 bit (Код Обмена Информацией, 7 бит) which means "Code for Information Exchange, 7 bit".[1]

It was first standardized in GOST 13052-67 (with the 2nd revision GOST 13052-74 / ST SEV 356-76) and GOST 27463-87 / ST SEV 356-86.

Shift Out (SO) and Shift In (SI) control characters are used in KOI-7, where SO starts printing Russian letters (KOI-7 N1), and SI starts printing Latin letters again (KOI-7 N0), or for lowercase and uppercase switching. This version is also known as KOI7-switched aka csKOI7switched.[2][3]

On ISO 2022 compatible computer terminals KOI7-switched can be activated by the escape sequence ESC ( @ ESC ) N LS0.[2]

KOI-7 was used on machines like the SM EVM (СМ ЭВМ) and DVK (ДВК); KOI-7 N2 was utilized in the machine-language of the Электроника Д3-28 [ru] (Elektronika D3-28) as four-digit hexadecimal code, БЭСМ-6 [ru] (BESM-6), where it was called ВКД, (internal data code). The encodings were also used on RSX-11, RT-11 and similar systems.[4]

KOI-7 N0[edit]

KOI-7 N0[2] (КОИ-7 Н0[1]) is identical to the IRV set in ISO 646:1967.[2] Compared to US-ASCII, the dollar sign ("$") at code point 24 (hex) was replaced by the universal currency sign "¤", but this was not maintained in all cases, in particular not after the fall of the Iron Curtain. Likewise, the IRV set in ISO/IEC 646:1991 also changed the character back to a dollar sign.

KOI-7 N1[edit]

KOI-7 N1 (КОИ-7 Н1[1]) was first standardized in GOST 13052-67,[5][6][7] and later also in ISO 5427.[2] It is sometimes referred to as "koi-0" as well.[6]

Compared to ASCII and ISO 646 uppercase and lowercase letters are swapped in order to make it easier to recognize Russian text when presented using ASCII.[6]

To trim the alphabet into chunks of 32 characters the dotted Ё/ë was dropped.[6] In order to avoid conflicts with ASCII's and ISO 646's definition as DEL and its usage as EOF marker (-1) in some systems, it dropped the "CAPITAL HARD SIGN" Ъ that would have naturally resided at this location.[6]

In a Bulgarian variant the unnecessary Russian "CAPITAL YERY" Ы at code point 121 was replaced by the "CAPITAL HARD SIGN" Ъ.[6]

KOI-7 N2[edit]

KOI-7 N2 (КОИ-7 Н2[1]), like KOI-7 N1, was also standardized in GOST 13052-67.[7]

Kermit names it SHORT-KOI / short-koi.[8][9]
