KOI8-U is an 8-bit character encoding, designed to cover Ukrainian, which uses the Cyrillic alphabet. A character encoding consists of a code that pairs a sequence of characters from a given character set (sometimes incorrectly referred to as Code page Ukrainian (in Ukrainian украї́нська мо́ва ukrayins'ka mova,) is a language of the East Slavic subgroup of the Slavic languages. The Cyrillic alphabet (səˈrɪlɪk also called azbuka, from the old name of the first two letters is actually a family of Alphabets, subsets of which are used by It is based on KOI8-R, which covers Russian and Bulgarian, but replaces eight graphic characters with four Ukrainian letters Ґ, Є, І, and Ї in both upper case and lower case. KOI8-R is an 8-bit Character encoding, designed to cover Russian, which uses the Cyrillic alphabet Russian ( transliteration:,) is the most geographically widespread language of Eurasia, the most widely spoken of the Slavic languages Bulgarian (български език IPA: ɛzˈik is an Indo-European language, a member of the Slavic linguistic group Ge (Ґ ґ italic Ґґ) is a letter of the Cyrillic alphabet mainly used in Ukrainian, representing the Ye (Є є is a letter of the Cyrillic alphabet, used in Ukrainian and Rusyn languages to represent the iotated vowel sound /je/ I (І і (also called dotted I) is a letter of the Cyrillic alphabet, used in the orthographies of the Belarusian, Kazakh and Yi (Ї ї is a letter of the Cyrillic alphabet, used in the Ukrainian and Rusyn languages
KOI8 remains much more commonly used than ISO 8859-5, which never really caught on. ISO 8859-5, also known as Cyrillic is an 8-bit Character encoding, part of the ISO 8859 standard Another common Cyrillic character encoding is Windows-1251. Windows-1251 is a popular 8-bit Character encoding, designed to cover languages that use the Cyrillic alphabet such as Russian, Bulgarian and In the future, both may eventually give way to Unicode. In Computing, Unicode is an Industry standard allowing Computers to consistently represent and manipulate text expressed in most of the world's
In Russian, KOI8 stands for Kod Obmena Informatsiey, 8 bit (Код Обмена Информацией, 8 бит) which means "Code for Information Exchange, 8 bit".
The KOI8 character sets have the property that the Russian Cyrillic letters are in pseudo-Roman order rather than the natural Cyrillic alphabetical order as in ISO 8859-5. Although this may seem unnatural, it has the useful property that if the 8th bit is stripped, the text can still be read (or at least deciphered) in case-reversed transliteration on an ordinary ASCII terminal. For instance, "Русский Текст" in KOI8-U becomes rUSSKIJ tEKST ("Russian Text") if the 8th bit is stripped.
