Thread:Project:Support desk/Sorting Tibetan content in Category page

Hi! i am trying to create a wiki with Tibetan language content. I use MediaWiki	1.22.2, PHP 5.4.23 (fpm-fcgi) and MySQL	5.1.66-0+squeeze1-log. I have trouble sorting pages in category pages in tibetan alphabetical order. If i understand correctly $wgCategoryCollation does not support tibetan specifically (uca-bo does not seem to be among the 68 recognized langcode). Do you see another way to achieve a correct sorting? I have noticed some wiki which have managed to do it... In particular: http://www.rigpawiki.org/index.php?title=Category:Tibetan-English_Dictionary&until=%E0%BD%80%E0%BE%B3%E0%BD%BC%E0%BD%84%E0%BC%8B%E0%BD%86%E0%BD%BA%E0%BD%93%E0%BC%8B%E0%BD%A6%E0%BE%99%E0%BD%B2%E0%BD%84%E0%BC%8B%E0%BD%90%E0%BD%B2%E0%BD%82%E0%BC%8B. Sorry to bother you with such a specific question...
