Thread:Project:Support desk/Short URLs not working after upgrade from 1.19 to 1.23/reply

I found something related in the HISTORY file:

using like nginx, lighttpd, and apache over fastcgi. MediaWiki now always extracts path info from REQUEST_URI if it's available.
 * `$wgUsePathInfo = true;` is no longer needed to make $wgArticlePath work on servers

Which corresponds to this: _SERVER["REQUEST_URI"] = "/HlavnĂ­_strana" _SERVER["QUERY_STRING"]	= "title=Hlavn%C3%AD_strana"

It seems, that while the article name is correct in _SERVER["QUERY_STRING"] variable, the _SERVER["REQUEST_URI"] contains it invalid encoded.
