Reproduction would likely require installing and configuring fcitx, if
you're willing to do that. It's 100% reproducible, and I've started
Emacs like this for many years in order to make it work:

env LC_CTYPE=zh_CN.UTF-8 /home/eric/dev/emacs/src/emacs

I thought that might cause other weirdness in Emacs, but it never did,
not that I noticed.

Actually, I'm running the pgtk branch as my daily driver now, maybe it's
time to remove that incantation and see if anything's changed.
