KOI-8

KOI-8 (short for "Kod Obmena Informatsiey 8-bit") is a character encoding system used for representing the Cyrillic alphabet, primarily for the Russian language. It is an 8-bit encoding that includes 128 characters from the ASCII set along with additional characters needed to represent various letters and symbols used in Cyrillic scripts. The KOI-8 encoding was developed in the 1980s and was widely adopted in Russia and other countries using the Cyrillic alphabet.
