ISO 9
The ISO international standard ISO 9 establishes a system for the transliteration into Latin characters of Cyrillic characters constituting the alphabets of many Slavic and non-Slavic languages.[1]
Published on February 23, 1995,[2] the major advantage ISO 9 has over other competing systems is its univocal system of one character for one character equivalents (by the use of diacritics), which faithfully represents the original spelling and allows for reverse transliteration, even if the language is unknown.
Earlier versions of the standard, ISO/R 9:1954, ISO/R 9:1968 and ISO 9:1986, were more closely based on the international scholarly system for linguistics (scientific transliteration), but have diverged in favour of unambiguous transliteration over phonemic representation. The edition of 1995 supersedes the edition of 1986.[1]
ISO 9:1995
[3] The standard features three mapping tables: the first covers contemporary Slavic languages, the second older Slavic orthographies (excluding letters from the first), and the third non-Slavic languages (including most letters from the first). Several Cyrillic characters included in ISO 9 are not available as pre-composed characters in Unicode, neither are some of the transliterations; combining diacritical marks have to be used in these cases. Unicode, on the other hand, includes some historic characters that are not dealt with in ISO 9.
Transliteration table
The following combined table shows characters for various Slavic, Iranian, Romance, Turkic, Uralic, Mongolic, Caucasian, Tungusic, Paleosiberian and other languages of the former USSR which are written in Cyrillic.

Sample text
The text is the chorus of the hymn of the Russian Federation:
Славься, Отечество наше свободное, Братских народов союз вековой, Предками данная мудрость народная! Славься, страна! Мы гордимся тобой! |
Slavʹsâ, Otečestvo naše svobodnoe, Bratskih narodov soûz vekovoj, Predkami dannaâ mudrostʹ narodnaâ! Slavʹsâ, strana! My gordimsâ toboj! |
ISO/R 9
ISO Recommendation No. 9, published 1954 and revised 1968, is an older version of the standard, with different transliteration for different Slavic languages, reflecting their phonemic differences. It is closer to the original international system of Slavist scientific transliteration.
A German adaptation of this standard was published by the Deutsches Institut für Normung as DIN 1460 (1982) for Slavic languages and supplemented by DIN 1460-2 (2010) for non-Slavic languages.
The languages covered are Bulgarian, Russian, Belarusian, Ukrainian, Serbo-Croatian and Macedonian. For comparison, ISO 9:1995 is shown in the table below.
Alternative schemes: ISO/R 9:1968 permits some deviations from the main standard. In the table below, they are listed in the columns alternative 1 and alternative 2.
- The first sub-standard defines some language-dependent transliterations for Belarusian (BE), Bulgarian (BG), Russian (RU), and Ukrainian (UK).
- The second sub-standard permits, in countries where tradition favours it, a set of alternative transliterations, but only as a group. It is identical to the British Standard 2979:1958 for Cyrillic romanization.[17]
