That link works.  As I mentioned above, I'm not having a problem with the localization of the editor itself.

The problem is that if I want to populate the editor with Japanese characters (as I've pictured in the first post of this thread), it doesn't work.

 

I don't think I can host an example online, but the picture does all the necessary exaplaining.  Our original editor shows the Japanese characters just fine.  The CE shows the Japanese characters for the localization fine, but does not convert the Japanese characters in the editor itself.
