SCREEN() function doesn't make nice with _FONT in graphic modes

[sivacc]

I am using  Indic  script . As you are using Font statements, you can help me , I am sure  . I can print correctly in Libre Office, but not in QB64pe, versions 3.6 as well as 3.7 . The example under _UPrintstring in Russian ,  in 3.7 ran correctly, but when I substituted the font and the DATA,  print was wrong. I will be grateful for  any suggestion .Thanks a lot
