I found the way to show Cyrillic letters on screen. I use roImageCanvas and
CP1251 font. To show russian text on e.g. roPosterScreen I show roPosterScreen, and then transparent roImageCanvas above it, where I put Russian text. Check out
https://owner.roku.com/add/7ENBQ, click on any TV channel, to see the screen with russian text.
The problem here is that roImageCanvas takes all input from remote. How can I redirect input from remote to roPosterScreen which is underneath?
Or may be there is a way to put my font to roPosterScreen?
