PanGorilla Font Selection Still Elusive

[PagCal <pagcal runbox com>]

Dudes, I still don't have PanGorilla selecting the proper CJK fonts yet. 
Is it true it was debugged for Latin fonts, but not CJK? It seems so.

The nexis subroutine for the solution to this problem seems to be 
pango_fc_font_map_get_patterns.

Finding it was no easy matter, as you have publised no architecural 
documentation, nor is the code documented, even to the point of a proper 
BNF for the one font selection routine the user has available. Shame on you!

In any event, it seems that this routine calls the libfontconfig 
function FcSort and friends, but not before it builds an FcPattern up 
from user input, then quick callbacks to GTK2 and Xft2.

But, I note the routine in question doesn't consider LANG, as in 'export 
LANG=zh_CN' or whatever. However, once FcSort is called, libfontconfig 
does consider the 'language' string a make or break font attribute. LANG 
is getenv'd by libfontconfig however, whenever you call FcMatch and 
friends, so it gets set and used (mostly) properly there.

This is probably a bug you should fix, or at least come up with a decent 
document detailing how PanGorilla ends up with a particular font.

What role does /etc/pango/pangox.aliases play in all of this?

As for /etc/fonts/fonts.conf, I had to add 'MS Song' a few places before 
I could get PanGorilla/libfontconfig to even consider using them, so it 
seems out-of-date.
