I can't input Japanese with fcitx-mozc IME on Konsole and Kwrite. On the other hand, I can input Japanese on Firefox using fcitx-mozc. Reproducible: Always Steps to Reproduce: 1. sudo apt install fcitx-mozc 2. KDE menu > Applications > Settings > Input Method Configuration > Imput method tab > Add(+) Mozc > Global config tab > Trigger Input Method > Ctrl+Space 3. Run Konsole or Kwrite. 4. Press |Ctrl+Space| key to turn on the IME. 5. Press |a| key. Actual Results: It doesn't turn on the IME. So, Konsole(or Kwrite) shows |a| character directly. Expected Results: Konsole(or Kwrite) shows |あ| character via the IME.
