Template:Short description Template:Infobox character encoding KOI8-R (RFC 1489) is an 8-bit character encoding derived from the KOI-8 encoding by the programmer Andrei Chernov in 1993 and designed to cover Russian, which uses the Russian subset of a Cyrillic script. KOI-8, on its turn, is an 8-bit extension of the KOI-7 encoding, which inherited a phonetic correspondence of Russian and Latin letters from the MTK-2 teletype code. As a result, Russian Cyrillic letters in KOI8-R are in pseudo-Latin alphabetical order rather than the normal Cyrillic one like in ISO 8859-5. Although this may seem unnatural, this has the useful effect that if the 8th bit is stripped, the text remains partially readable in any ASCII-based encoding (including KOI8-R itself) as a case-reversed transliteration. For example, "Код для обмена и обработки информации" (the Russian meaning of the "KOI" acronym) becomes kOD DLQ OBMENA I OBRABOTKI INFORMACII.
KOI-8 stands for 8-bitnyy kod dlya obmena i obrabotki informatsii (Template:Langx) which means "8-Bit Code for Information Interchange".[1] In Microsoft Windows, KOI8-R is assigned the code page number 20866. In IBM, KOI8-R is assigned code page 878.[2][3] KOI8-R also happens to cover Bulgarian.
It lacks proper quotation marks for these languages: both «...» and the Bulgarian „...“. Windows-1251 does support these, as well as more letters, and has thus become more popular. KOI8-R is used by less than 0.004% of websites, mostly Russian and Bulgarian.Script error: No such module "Unsubst". Unicode and UTF-8 is preferred to single-byte Cyrillic encodings in modern applications, Unicode contains 436 Cyrillic letters including for Old Cyrillic.
Character set
The following table shows the KOI8-R encoding. Each character is shown with its equivalent Unicode code point.
