Is there a way to check which one is currently in use? There must be. So Russians are slacking on this one? Also they could check in which language are files and folders named or they could check timezone or something. Years ago I loved to read malware RE articles and I remember they also checked for Belarussian, Ukrainian and most of the ex-USSR countries' languages. Isn't the most efficient way to check external IP address of the device, ofc if it has one.
