      Sets the font used for subsequent text and symbols.  For devices
      that still use Hershey fonts this routine has no effect unless the
      Hershey fonts with extended character set are loaded (see plfontld).
      For unicode-aware devices that use system fonts instead of
      Hershey fonts, this routine calls the plsfci routine with argument set up
      appropriately for the various cases below.  However, this method of
      specifying the font for unicode-aware devices is deprecated, and the much
      more flexible method of calling plsfont directly is recommended
      instead (where plsfont provides a user-friendly interface to plsfci),
