Using FCITX to input Chinese

Before you can take use of FCITX to input, you have to set up some environment firstly, however it's quite simple.

  • Open .bashrc file in your home directory, add following lines:
 #setup XIM environment, needn't if use SCIM as    gtk-immodules
 export XMODIFIERS=@im=fcitx
 export GTK_IM_MODULE=xim
 export QT_IM_MODULE=xim
  • Re-login to make such environment effective.

After you re-login, open your favorite terminal, type:

  fcitx &

To see if fcitx has been correctly running, open an application such as leafpad, press CTRL+Space to invoke fcitx and input some words.

If anything goes well, I guess you want to automatically start FCITX whenever you start X, which also is highly recommended since if you start FCITX after X, which may crash gnome-panel for example sometimes (not seriously but annoying). Open .xinitrc file in your home directory, add line before starting your WM:

 fcitx &

that's it.

If you use any type of XDM (gdm for example), you should set up such environment in ~/.profile instead of above two files.

Enjoy!

Troubleshooting:

You possibly can't invoke FCITX by press CTRL+Space keyboard combination, but FCITX runs in background without problem, please check firstly your locale:

 [ganlu@A ~]$ locale
 LANG=en_US
 LC_CTYPE=en_US.utf8
 LC_NUMERIC="en_US"
 LC_TIME="en_US"
 LC_COLLATE=C
 LC_MONETARY="en_US"
 LC_MESSAGES="en_US"
 LC_PAPER="en_US"
 LC_NAME="en_US"
 LC_ADDRESS="en_US"
 LC_TELEPHONE="en_US"
 LC_MEASUREMENT="en_US"
 LC_IDENTIFICATION="en_US"
 LC_ALL=

Above is what I get from command 'locale', so you can know for sure FCITX does support utf8 (en_US.utf8 at least) locale without problem. If you locale output shows you having set up a utf8 locale correctly, then I suggest you check if your bash does support utf8 locale:

[ganlu@A ~]$ locale -a

to see if your current locale in there, if not, don't worry, make it yourself:

[ganlu@A ~]$ localedef -vci en_US -f utf8 en_US.utf8

then, relogin to see if that works. If terrible things continue, I have to suggest you try any locale with "zh_CN", for example:

 export LC_CTYPE=zh_CN.gbk

more information about locale, please find it in google.

2. You can trigger FCITX, but the charactors on it is displayed as blank boxes. Modify ~/.fcitx/config, change the line:

显示字体(中)=*

as

显示字体(中)=AR PL ShanHeiSun Uni

I am using uming font here. Restart FCITX:

[ganlu@A ~]$ pkill fcitx
[ganlu@A ~]$ fcitx &


All configuration of FCITX, please find it in ~/.fcitx/config however you'd better understand Chinese, :- )
