Bug ID: 50774
           Summary: DirectWrite should use mac platform name entry for
                    English, if Windows entry is missing
           Product: Wine
           Version: 6.3
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dwrite
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

While testing patch [1] it became apparent that mac name entries should be used
more often. For a font from fonts-femkeklaver [2] English face name entry
exists for mac platform only. We should pick it up as well.

P.S. additional improvement would be to lowercase locale names.
