ДКОИ (Russian: ДКОИ, Двоичный Код Обработки Информации, "Binary Code for Information Processing") is an Telegraphy-based encoding used in ES EVM mainframes.[1][2] It has been defined by several standards: GOST 19768-74 / ST SEV 358-76, ST SEV 358-88 / GOST 19768-93,[3] CSN 36 9103.
There are two variants:
- DKOI K1 (ДКОИ К1), each Cyrillic letter is given its own code point.
- DKOI K2 (ДКОИ К1), some Cyrillic letters (А, В, Е, К, М, Н, О, Р, С, Т, Х, а, е, о, р, с, у, х) are merged with visually identical Latin letters (A, B, E, K, M, H, O, P, C, T, X, a, e, o, p, c, y, x). Code points 95 and 161 are negation
¬and overline‾instead of^and~.
In both variants the dollar sign $ may be placed in code point 91; in that case the currency sign ¤ is in code point 225. Such modification makes DKOI K1 similar to EBCDIC 880.
