I have just tried, and the contents of the font-log variable are
appended to this message.
Besides, WQY Micro Hei Mono is a useful font for Simplified Chinese.
No other font has
such beautiful glyphs for SC. And the font itself should not really
matter, a font is just a
set of curves, after all. If it is rendered incorrectly, it is a bug
in the rendering library, not
in the font. A library should accept every font imaginable.

fonts, but X users should not use PGTK.
I have both. I am usually using X, but this effect manifests itself on
Wayland too.
What is wrong about using pgtk with X?
GTK works on X.
