Cyrillic Romanization

Convert Cyrillic characters to Latin characters (transliteration).

Default transliteration works according to ISO 9:1995.

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

• Gaj's Latin alphabet transliteration is supported for Serbian, Macedonian, and Montenegrin alphabets;
• The -ia exception at the end of the 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;
• MNS 5217:2012 standard is supported for the Mongolian Cyrillic alphabet;
• For Russian and Belarusian languages is used GOST 7.79-2000 (B);
• Additional ALA-LC romanization system for Russian;
• The Ukrainian Cyrillic alphabet is transliterated into Latin by the Ukrainian national system based on BGN/PCGN 2019;
• For Uzbek romanization is used Latin-based alphabet of the proposed version from 2023.

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