Since proper category sorting seems to be working correctly in MediaWiki now (I have tested the uca-cs collation now (thanks to MediaWiki-Vagrant!), and it seems to work perfectly!), could we get proper Czech sorting in categories, please?
I.e. set
$wgCategoryCollation = 'uca-cs';
on all Czech-language wikis.
