This plugin will automatically transliterate permalink URLs when you save a new page or post with a title in the Cyrillic script.
Romanization presets are available for all the major languages using the Cyrillic script: Russian, Ukrainian, Kazakh, Belarussian, Serbian, Tajik, Bulgarian, Kyrgyz, Bosnian, Mongolian, and Macedonian.
The plugin can also romanize permalinks for any pre-existing posts, categories, products or other items with a title written in Cyrillic.
Only UTF-8 encoding is supported.
