This issue have from Wired Client v2.0.

The Japanese characters input 1char , using 2 and more keydown as follows.
ex) input "火" <- "k" key and "a" key and space key and enter key

In 'WCChatWindow.m', when keydown event occurred, the input force commit as "k" only.
The solution to this problem is to comment out as follows.
But I do not know the impact of doing this fix....
