This section includes information related to the support of various languages under Fedora Core.

iiimf

  • The default Input Method (IM) for Chinese (Simplified and Traditional), Japanese, and Korean has been changed to IIIMF - the Internet/Intranet Input Method Framework. IIIMF is supported as a native GTK2 IM module, and also through XIM using the httx client. IIIMF supports the use of multiple Language Engines (LEs) at the same time; using the GNOME Input Method Language Engine Tool (GIMLET - an applet) it is possible to switch between LEs of different languages inside GTK2 applications.

IIIMF currently defaults to using Ctrl-Space or Shift-Space for toggling the input method on and off (Emacs users can use Ctrl-@ instead of Ctrl-Space to set the mark.)

Depending on your selection at the language support screen during installation, one or more IIIMF language engines may be installed. The IIIMF server package (iiimf-server) will also be installed if a language engine has been selected. The language to language engine (LE) package mappings are as follows:

  • ja_JP - iiimf-le-canna
  • zh_CN - iiimf-le-chinput
  • zh_TW - iiimf-le-xcin
  • ko_KR - iiimf-le-hangul
  • {bn,gu,pa,ta,hi}_IN - iiimf-le-unit

Accordingly, input via IIIMF will be enabled if you have chosen one of the following as your default locale:

  • ja_JP
  • zh_CN
  • zh_TW
  • ko_KR
  • {bn,gu,pa,ta,hi}_IN

To aid your use of IIIMF, if you have selected one of the above locales and you are using the GNOME Desktop, when you first login the GIMLET utility (part of the iiimf-gnome-im-switcher package) will automatically be added to your panel.

GIMLET is a utility for switching between the different LEs that are installed on your system. Using a different language engine allows you to enter text in different languages. Alternatively you may add GIMLET manually to your panel by right clicking on the panel and selecting:

Add to Panel -> GIMLET

Should you wish to switch between IIIMF or the legacy input method framework XIM, you can use the system-switch-im application. After changing the input method framework your changes will be reflected when you next start the X Window System.
