Foreign language support

I am playing my European routes more of late and downloaded the latest offerings and updates from Czech Republic, France, Greece and Russia.
When checking these routes, it appears RW_Tools has trouble displaying accented letters like in Czech or French or letters belonging to the Greek and Cyrillic alphabets.
Especially scenarios that contain destination markers in non-English aren't shown at all, this affects the Russian routes.
The Russian names in the scenario selection in Railworks and on the "9" map are shown in Cyrillic proper.
Is there a solution since the Russian routes crash and I cannot check them. I suspect the odd Cyrillic character has been inserted in some asset paths probably.
Non-US Windows versions have all character sets installed, and Greek and Russian texts display OK in internet browsers, etc.
