From 64a4a336142d15b00bb82d15e92dc8634c2b7db1 Mon Sep 17 00:00:00 2001 From: Jihoon Kim Date: Mon, 26 Dec 2011 04:25:55 +0000 Subject: [PATCH] From: Jihoon Kim Subject: Re: [E-devel] [PATCH] scim-EFL immodule I'd like to contribute EFL-scim immodule. It will be useful to users who wants to input Chinese, Japanese, Korean, and a variety of languages that SCIM provides.
