This International Standard establishes a system for the transliteration into Latin characters of Cyrillic characters constituting the alphabets of Slavic and non-Slavic languages, in accordance with the principles of stringent conversion in order to permit international information exchange, particularly by electronic means. For the transliteration of Slavic Cyrillic characters, tables 1 and 2 reproduce the tables published in the first edition of ISO 9:1986; for the transliteration of Cyrillic characters constituting the alphabets of non-Slavic languages, table 3 adopts the transliteration of tables 1 and 2 for all characters similar to those of Slavic languages and gives equivalents for all supplementary characters introduced in the alphabets of non-Slavic languages. Table 3 includes in a single sequence, listed in the Cyrillic alphabetic order, the 118 single or diacritic-carrying characters that appear in one or another of the considered alphabets. The list of the languages written in these alphabets is given in annex C.
