Same for me on iOS App.
Server: ALT Linux 6.0 SPT x86_64 – nomachine-enterprise-server-evaluation_4.3.30_2_x86_64.rpm
Client: Ipad 3 with iOS 8.1, standard keyboard
Inside a session: I can’t type Russian in Chromium browser address bar or on web page edit boxes, for example.
But, if I change keyboard layout inside a session from En to Ru, than I can type Russian by English letters 🙂
