Yup, works fine! I now have pango.aliases contain:

courier = "courier new"
sans = "arial,mingliu,simhei,gulimche,ms gothic"
serif = "times new roman,mingliu,simsun,gulimche,ms gothic"
monospace = "courier new,mingliu,simhei,gulimche,ms gothic"

and when starting testgtk with LANG=zh_TW, the colorselector uses
mingliu:

with LANG=zh_CN, it uses simhei:

and for Japanese, ms gothic:

(I don't think mingliu necessarily is the best choice for blending
visually well with the arial font used for the latin characters in
"sans". But the main point is visible: depending on locale, a correct
font is chosen for the unihan characters.)

(I also used a gtkrc that set the default font_name to sans 18 to see
the differences better.)

I had to add an #ifdef G_OS_WIN32 section to
gtkmain.c:gtk_get_default_language(), because he setlocale() in
Microsoft's C library doesn't return the sv_FI style locale codes, but
Swedish_Finland etc. On Win32, you have to use g_win32_getlocale().
