[xwiki-users] non-english languages

Hello everybody! I'm try to using XWiki 0.9.840 in the own projects, but have a lot of problem with Russian text. Maybe I do something wrong, so please help me if possible. I'm using KOI8-R encoding in XWiki. Russian text is edited and viewed correctly. 1. But it's impossible to search on the Russian - search box contains "????" after Sumbit. Looks like incorrect encoding is used. 2. When I try to use Lists Syntax - it's not working at all. Some lines are displayed as bold, some lines as regular text. 3. It's impossible to create new page with Russian name. It's always saved as "?????". Thank you for your comments!
