Fontconfig - Nov 2005 - which font will be chosen?

hi,

in a gtk2 program...gedit for example:
let''s say i select "arial" as my font.
it works fine.

now i enter some japanese text. arial does not contain the necessary
glyphs. but gedit is able to find a "suitable" font and use it to
display those glyphs.


question:
i have 5-10 japanese ttf fonts. which one will be picked? and how can i
adjust it?

(i assume that fontconfig does this job...or pango?)


thanks a lot,
gabor farkas
