      Issue:

      We are currently in the process of updating to Qt6.9 from Qt5.15 and have noticed that the font family "Segoe UI Semibold" (among others) is no longer available.

      It works if "-platform windows:nodirectwrite" is specified.

      Findings:

      <EnumFontFamiliesEx> is used in both <QWindowsFontDataBase> and <QWindowsDirectWriteFontDatabase> to collect all system available fonts.

      However, in <QWindowsDirectWriteFontDataBase> only raster type fonts are registered which causes "Segoe UI Semibold" to be ignored.

      Questions:

      Is this an actual issue or is this somehow intentional ?
