what someone did

After installing manjaro, the following is what I did to enable you to enter Japanese.

• fcitx-mozc
• fcitx-gtk2
• fcitx-gtk3
• fcitx-qt4

export LANG="ja_JP.UTF-8"
exportXMODIFIERS="@im=fcitx"
exportXMODIFIER="@im=fcitx"
export GTK_IM_MODULE=fcitx
export QT_IM_MODULE=fcitx
exportDefaultIMModule=fcitx

export GTK_IM_MODULE=fcitx
exportXMODIFIERS=@im=fcitx
export QT_IM_MODULE=fcitx

You can switch between Japanese and half-width alphanumeric characters using "zenkakuhanankaku" and "ctr+space key" without any problems when using it normally (this question as well).

Question

"However, when I click the ""a"" icon while typing in Japanese and click ""Mozc tool"" --> ""dictionary tool"" switches to half-width alphanumeric input, and I am having trouble registering Japanese words because it does not input in Japanese."

If anyone knows the solution, please let me know.
