Letter spacing & russian fonts

Hi friends,
In my game I'm using many languages and russian also but I have a issue with it, every language work's fine with the font and font size, but when I change my game in russian the text acts "crazy" becoming very big and the font is not the same . The second issue is letter spacing in new Unity UI System we don't have the possibility to control the space between the letters...I think this feature will be much appreciated ! Hope I will get some help or guidance from you uniters, thanks !
