C++ Builder Xe with Quick report on translating print report

I am using QR report 506 along with C++ Builder. The base language of the software is German. After print preview if I save the report as pdf in German language it is saving as it is. When the same is done in Russian version of the software instead of displaying the translated texts in Russian, it is displaying “????”.
What might be the reason? Can you provide a solution to fix it?
