Classification Extended ASCII
Extensions ISO-8859-5, IBM-1124, ISO-IR-200, ISO-IR-201

ISO-IR-153[1] (ST SEV 358-88) is an 8-bit character set that covers the Russian and Bulgarian alphabets. Unlike the KOI encodings, this encoding lists the Cyrillic letters in their correct traditional order. This has become the basis for ISO/IEC 8859-5 and the Cyrillic Unicode block.

Standards

ISO-IR-153 is a subset of ISO/IEC 8859-5 (synchronised with ECMA-113 since 1988).[2] Whilst the ISO-IR-153 documentation cites the earlier GOST 19768-74[1] (which defines KOI-8 and was conformed to by the first version of ECMA-113, i.e. ISO-IR-111),[2] it does not follow the KOI-8 layout so this appears to be in error. It also cites ST SEV 358-88.[1]

Character set

The following table shows the ISO-IR-153 encoding. Each character is shown with its equivalent Unicode code point and its decimal code point.
