KOI-8
KOI-8 is an 8-bit character set standardized in GOST 19768-74. It is an extension of KOI-7 which allows the use of the Latin alphabet along with the Russian alphabet, both the upper and lower case letters, however, the letter Ёё and the uppercase Ъ are missed, the latter to avoid conflicts with the delete character. The first 127 code points are identical to ASCII with the exception of the dollar sign $ replaced by the universal currency sign ¤. The rows x8_ and x9_ might be filled with the additional control characters from EBCDIC.
This standard has become the base for the later Internet standards such as KOI8-R, KOI8-U, KOI8-RU and all the other derivatives.Character set
