Using ibus input methods in Emacs GTK+

[Luis Felipe]

Hello,

I upgraded my Guix system (currently on 17fadbb) and now I can type 
Japanese again (thanks, 宋文武). However, ibus input methods are working 
everywhere (GTK, GTK+, Qt) except in Emacs GTK+, which is unexpected 
because typing Japanese in Emacs used to just work before.  My current 
workaround is to start "emacs -nw" in a GNOME Console and then I can use 
ibus in it.

I thought that maybe something in Emacs 28.x had changed, but trying on 
a Debian 12 machine, I can use ibus normally in Emacs GTK+ without 
configuring anything.

If you're able to type Japanese (or use ibus input methods in general) 
in Emacs GTK+, did you have to do anything special?

Thanks,
