Hi,
 
I came across this bug report as I was having the same problem, and I
also thought there was a bug in Emacs, as fcitx5 works great everywhere
else.

Note I'm using fcitx5 so it may not be exactly the same for you.

> Specifically:
> ➜  ~ cat .xprofile
> export XMODIFIERS=@im=fcitx
> export QT_IM_MODULE=fcitx
> export GTK_IM_MODULE=fcitx
> export LC_CTYPE=zh_CN.UTF-8

Apparently these settings should be enough for every application to
work, but when it doesn't work on some application, there is a bigger
hole you have to dig into than simply looking at whether the environment
variables are set properly - because they are, and Emacs respected it, fcitx5
just didn't work in Emacs due to other reasons.

You have to fully utilize `fcitx5-diagnose` to see what is wrong.
1. Open a subshell within Emacs, run `fcitx5-remote` to see if fcitx5 is
    surely not enabled.
2. Run `fcitx5-diagnose` in the subshell *and* outside Emacs (in a
    regular terminal), compare the results, look for errors

I also got help from the fcitx5 maintainer:
    https://github.com/fcitx/fcitx5/issues/402


Anyways at the end of the day I'm using fcitx5 in Emacs, so I believe this bug
    report should be closed.
