I use fcitx-mozc for typing Japanese and I would like to use it in emacs over the inbuilt as it is more powerful.
I tried using mozc-mode (mozc.el) but that says there's "communication error with the helper process".
I tried using fcitx.el and
(fcitx-aggressive-setup)
(setq fcitx-use-dbus t)
to my .emacs file and ran fcitx-aggressive-setup
but neither work.
