Mojibake may be colloquially called ( ) in Russian, which was and remains complicated by several systems for encoding Cyrillic. The Soviet Union and early Russian Federation developed KOI encodings (, , which translates to "Code for Information Exchange"). This began with Cyrillic-only 7-bit KOI7, based on ASCII but with Latin and some other characters replaced with Cyrillic letters. Then came 8-bit KOI8 encoding that is an ASCII extension which encodes Cyrillic letters only with high-bit set octets corresponding to 7-bit codes from KOI7. It is for this reason that KOI8 text, even Russian, remains partially readable after stripping the eighth bit, which was considered as a major advantage in the age of 8BITMIME-unaware email systems. For example, words "" , encoded in KOI8 and then passed through the high bit stripping process, end up rendered as "[KOLA RUSSKOGO qZYKA". Eventually KOI8 gained different flavors for Russian and Bulgarian (KOI8-R), Ukrainian (KOI8-U), Belarusian (KOI8-RU) and even Tajik (KOI8-T).
