--- Comment #3 from Nikolay Sivov bunglehead@gmail.com --- If this is a Delphi/C++ Builder application, it was common back then for such applications to show question marks for Russian text UI, when running on locales other than Russian. To run them on Wine use LANG=ru_RU.UTF-8, assuming it's the same issue.
