Cyrillic Romanization

Convert Cyrillic characters to Latin characters (transliteration).

Default transliteration works according to ISO 9:1995 regardless of the language.

However, ISO 9 is rarely used in practice because it has unusual diacritical letters. Thus:

• Gaj's Latin alphabet transliteration is supported for the Serbian, Macedonian, and Montenegrin alphabets;
• The Azerbaijani transliteration uses the contemporary form of the grapheme schwa instead of A-diaeresis (1992);
• The -ia exception at the end of a word is supported for Bulgarian transliteration;
• The Kazakh transliteration follows the Decree of the President of the Republic of Kazakhstan dated October 26, 2017, No. 569, 2021 revision;
• The MNS 5217:2012 standard is supported for the Mongolian Cyrillic alphabet;
• For Russian and Belarusian, GOST 7.79-2000 (B) is used;
• An additional ALA-LC romanization system is supported for Russian;
• The Turkmen transliteration uses contemporary conventional letter symbols (1999);
• The Ukrainian Cyrillic alphabet is transliterated into Latin by the Ukrainian national system based on BGN/PCGN 2019;
• For Uzbek romanization, the Latin-based alphabet is used (proposed version from 2023).

Be aware that the presented romanization rules are unsuitable for the transliteration of geographic names.
