I did get the mail from gtk-i18n-list, so it seems to be working
in terms of posting.

Hmm, I'm a bit puzzled. One thing to check is to see if the
encoding of your fonts matches the encoding that the module
expects - though that isn't anything very fancy. (Just a 256
character fonts with the high characters having the Thai characters
as in the TIS standard.)

Actually, most likely the problem is that it isn't looking
for the font to begin with.

You probably want to to copy the installed
$(sysconfdir)/pango/pangox.aliases to the various aliases in
~/.pangox.aliases and then add your font.

(A possible alternative would be to make "lucidaz" instead of "sans"
the default GTK+ font by creating a ~/.gtkrc.-2.0 that looks something
like:

style "user-font"
{
  font_name="lucidaz 12"
}
widget_class "*" style "user-font"

However, I think the testtext demo does reference "sans" explicitely
at least for some of the characters.)

Regards,
                                        Owen
