ISO-IR-153[2] (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[edit]

ISO-IR-153 is a subset of ISO/IEC 8859-5 (synchronised with ECMA-113 since 1988).[3] The ISO-IR-153 documentation cites ST SEV 358-88 as the source standard.[2] While it also cites the earlier GOST 19768-74[2] (which defines KOI-8 and was conformed to by the first version of ECMA-113, i.e. ISO-IR-111),[3] it does not follow the KOI-8 layout so this appears to be in error. The ISO-IR-153 encoding was intended to replace GOST 19768-74, and is sometimes referred to as GOST-19768-87.[1][4]
