You hardly can make Russin input with keyboard - there are no hardware Cyrrilic support by Motorola on HW level.
But you can make your own software keyboard with Wavelink Keyboard Creator, map SW keys to proper codes.
Scan input with Unicode should be handled carefully, as for today there are no support fot its correct processing in core Motorola libraries (Wavelink does use it). Possible way is to get data from scanner as is, convert it to required code page, then send to input or whatever. It works, confirmed : )
