Can't input Japanese

[Inqb8tr-jp]

Hi, Thank you for making qolibri. I can't input Japanese character on qolibri under Manjaro Linux. I use fcitx5-moz for Japanese input system. I installed qolibri with yay. qolibri's version: 2.1.4 Qt version: 5.15.5

When I encounterd input problem with Anki, installing fcitx-qt5 resolved the problem. But in this case, it doesn't work.

fcitx-qt5 is for Fcitx 4 and won't help here. I reckon it doesn't work in any Qt applications, not just qolibri.

I was curious about Manjaro anyway, so I spun up a Manjaro Plasma VM and did a yay -S qolibri.

The following fcitx packages are installed:

$ pacman -Qqe | grep fcitx
fcitx5-configtool
fcitx5-gtk
fcitx5-mozc
fcitx5-qt

IME settings look like this, I just added Mozc without touching any other settings:

These environment variables are also needed:

$ cat ~/.xprofile
export GTK_IM_MODULE=fcitx
export QT_IM_MODULE=fcitx
export XMODIFIERS='@im=fcitx'

Voilà:

Firstly sorry for wrong typed fcitx-qt5 instead of fcitx5-qt. I've installed fcitx5-qt already. And thank you for such a detailed explanation.

Now I can find the reason why I can't input Japanese. I evoke qolibri from a toolbar icon of my Manjaro Xfce. But the execution doesn't pass LC_CTYPE=ja_JP.UTF-8 to qolibri.

I made a bash script below as a workaround and designate it to the icon but failed somehow.

#!/usr/bin/bash 
LC_CTYPE=ja_JP.UTF-8 qolibri

By changing LC_CTYPE with LANG, qolibri's interface change into Japanese. So the script is fine. But the problem is not qolibri related probably.

Anyway when I evoke qolibri from terminal, I can input Japanese.

By the way, I've installed qolibri on my arm64 ChromeOS's debian container by building deb file too, and works fine. Thank you.

LC_CTYPE and LANG should not affect the IME. Your next finding suggests it's an envvar problem though:

This sounds like the QT_IM_MODULE etc. envvars are set in your shell but not for the window manager. Maybe they're in your .bashrc or similar only? If you put them into ~/.xprofile or ~/.xinitrc and log out and back in, it should work. For further troubleshooting, you can print the environment of a running qolibri process like this:

$ strings /proc/$(pidof qolibri)/environ

This could help confirm if the variables are indeed missing when starting qolibri from the WM.

Thanks, that's great to hear!

Yes. I put environment variables into .bashrc. And after adding it to ~/.xprofile, qolibri accept Japanese input. Thank you so much and sorry for taking time for me.

No worries, I'd been meaning to check out Manjaro anyway. And I even found a bug (#52) in qolibri, so it's all good. Happy studying!
