Hi,
Last Saturday, I installed guile-1.3.4 and guile-gtk-0.17 into
my Linux box, and noticed that the latter would not recognize
"ja" (i.e., Japanese) locale. I used gtk-1.2.6.
Indeed you can display Japanese characters if you invoke
(gdk-set-locale) and (gtk-rc-parse "gtkrc.ja") within your
Scheme script, but you can never input Japanese characters via
X11's input method.
After all you have to invoke gtk_set_locale BEFORE gtk_init. I
modified the initialization routine as follows.

}

Now you can both display and input Japanese characters on the
GTK widgets if you are in "ja" locale; no hacking on Scheme
scripts is required. For example, the present "galway" as it is
seems Japanese-capable now! Of course, if you are in "C"
locale, the modified guile-gtk will behave exactly the same as
the original one.
I'd hope the next guile-gtk will pick up this modification.
Note that the pygtk of Python, a counterpart of the guile-gtk of
Guile, is implemented as follows, and thus locale-sensible (see
gnome-python-1.0.50/pygtk/gtk.py).
| # this sets up i18n input stuff
| _gtk.gtk_set_locale()
|
| # initialise GTK (only if it can find the display -- this avoids segfaults)
| if '--display' in sys.argv or os.environ.has_key('DISPLAY'):
| _gtk.gtk_init()
| else:
| print 'No display information -- gtk_init not called'
