I understand, that this is quite unusual problem, but here it is.
On my blog (http://dvicr.com) when trying to search blog with query consisting purely of cyrillic letters i run into problem - nothing is displayed. For example http://dvicr.com/?s=%F0%EE%E1%EE%F2%FB or http://dvicr.com/?s=робот returns nothing. English letters works just fine.
If I switch search form method to POST (as I did now) everything works fine. But the paging in search is broken then :(
Can anyone help?
I've tried tracking $_GET['s'] variable in wordpress, and it seems when it arrives at query.php it is already empty (if cyrillic letters are entered).
