Steps to Reproduce:
* <code>{{#language:sty}}</code> (get the native language name for Northern Tatar, whose ISO 639 code is 'sty')
* See [[https://commons.wikimedia.org/wiki/Module_talk:Multilingual_description/sort/testcases|test cases]] and click on the column for native names to see how it is sorted.
Actual Results:
* "cебертатар", where the initial is an incorrect **Latin** 'c' U+0063 (transcriptable to a Cyrillic letter 'к' or 'х')
* The language name currently sorts incorrectly with other names written in the Latin script, and **cannot** be found by plain text search with its normal Cyrllic orthography.
Expected Results:
* "себертатар'', where the initial is the correct **Cyrillic** 'c' U+0441 (transcriptable to a Latin letter 's'), or "Себертатар'' (if we want capitalization of the initial 'С' U+0421)
* The language name will sort correctly with other names written in the Cyrillic script and is found in plain text search.
