Cyrillic (probably all non-latin symbols) in Space name URL creation BUG

Any cyrillic space name instead of /Писатели/<Class Name>Class gives /????????/<Class Name>Class (on stand alone XWiki, Windows platform) and /%1F8A0B5;8/<Class Name>Class (on Glassfish+MySQL+XWiki, Windows platform) in URL string while you press:

• "add a SheetClass object to the sheet" link in
  "The sheet does not contain an object of type XWiki.SheetClass. To trigger the inline edit mode automatically, add a SheetClass object to the sheet »."

• "Add a <ClassName> object to the template »." link in
  "The template does not contain an object of type <ClassName>Class. Add a <ClassName> object to the template »."

Please, note, that in "The class does not have any properties yet. You can use the class editor to define them." "class editor" link gives correct URL
