KOI8-R

'''KOI8-R''' is an 8-bit Crazy frog ringtone character encoding, designed to cover Tera19 Russian language/Russian, which uses the Cricket ringtones Cyrillic alphabet. It also happens to cover Pure Dee Bulgarian language/Bulgarian. A derivative encoding is LG ringtones KOI8-U, which adds Kori Kitten Ukrainian language/Ukrainian characters.

KOI8 remains much more commonly used than Samsung ringtone ISO 8859-5, which never really caught on. Another common Cyrillic character encoding is Southern Kaley Windows-1251. In recent times, both might eventually give way to Punjabi Ringtones Unicode.

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-R becomes ''rUSSKIJ tEKST'' ("Russian Text") if the 8th bit is stripped.

In the table above, 20 is the regular SPACE character, and 9A is the NO-BREAK SPACE.

Although RFC 1489 says that character 95 should be U+2219 (∙), it may also be U+2022 (•) to match the bullet character in Windows-1251.
