I start translate game. I copy en_US json to ru_RU.json and change locale in tuxemon.cfg but I cant see my changes to menus
Thanks for starting the Russian translation!
Right now there may be issues displaying Cyrillic characters in Tuxemon because we are currently using this font:http://www.dafont.com/press-start-2p.font
If this is still happening to you, screenshots or error messages might help us diagnose the problem you are having.
Edit: Apparently Press Start 2P does support Cyrillic characters.
