No. Forget about old multi-byte encodings. Just set your locale to a UTF-8 locale and use UTF-8
for all languages. In my experience (on SuSE 7.3, 8.1, 8.2, and the 9.0 betas) all of the "important"
applications handle CJK languages perfectly well under a UTF-8 locale. The "important" applications
for me are things like Open Office 1.1, Konsole, vim, MySQL, and Mozilla. For CJK input, use SCIM
(http://ns.turbolinux.com.cn/~suzhe/scim/index.html). For many other details about Unicode
on Linux, see my page at http://eyegene.ophthy.med.umich.edu/unicode/index.html.

Most likely. But I think your life will be easier if you just use UTF-8 for all languages and forget about legacy
encodings. I'm sure ICU must have very robust UTF-8 support.
