On translatewiki.net the portal yua ( http://translatewiki.net/wiki/Portal:Yua ) is sorted under the letter U instead of Y in the categories 'Languages without translators', 'Languages' and 'Languages without Wikimedia projects'. It is also missing from the category 'ISO_15924:Latn' even though it is listed as a category at the bottom of the portal page.
$wgCategoryCollation = 'uca-default';
works after a nulledit, maybe some server issue at page creation time or so
