This reminded me that I used to have the same problem with xterm back
about two years ago. I had a fix and probably forgot to submit to the
upstream. I attach the patch at the end. It's against a very old version
of xterm (I have stopped using and following xterm for quit a while). Hope
it can be applied cleanly and fix your problem.

This one I have never seen. Just tried on a rh9 machine and couldn't
reproduce your problem. Will need more research later.

I don't think there's a way of doing it other than modifying the source
code.

Are you sure that you are using one of the traditional hanzi input method?
Try using Ctrl-Shift to switch input method see if you can get one with
traditional characters.
