I already have a patch to handle the translation on the backend
between the encoding and SJIS (yet another encoding for Japanese).
Translation for other encodings such as Big5(Chinese) and Unicode are
in my plan.

The biggest problem for Unicode is that the translation is not
symmetrical. An encoding to Unicode is ok. However, Unicode to an
encoding is like one-to-many. The reason for that is "Unification." A
code point of Unicode might correspond to either Chinese, Japanese or
Korean. To determine that, we need additional infomation what language
we are using. Too bad. Any idea?
