  68       The dual-width Asian fonts (spacing=dual) are not rendered correctly,
  69       apparently FreeType forces all widths to match. Trying to disable the
  70       width forcing code by setting globaladvance=false alone doesn't  help.
  71       As a brute force workaround, also set spacing=proportional, i.e. handle
  72       them as proportional fonts:  CJK 双宽度纠正

  86      There is a similar problem with dual width bitmap fonts. They don't
  87      have spacing=dual, therefore they are not handled by the above rule
  88      and still display as charcell fonts. For example "Efont Biwidth"
  89      has spacing=mono and "Misc Fixed Wide" has spacing=charcell.
  90      Force handling of these fonts as proportional fonts as well:
