Chinese And Japanese Characters In Same Colation

SQL 2000, latest SP. We currently have the need to store data from a
UTF-8 application in multiple languages in a single database.

Our findings thus far support the fact that single-byte and
double-byte characters can be held in the same DB without issue.
However, when holding two sets of DIFFERING double-byte characters
(i.e. Chinese and Japanese) there are issues.

Since Japanese has a superset of both Kanji and Katakana characters
it's our theory that the Japanese collations will hold Chinese as well
(Mandarin).

1) Has anybody tried to store multiple languages in the same db? What
collation was used?

2) Is it possible to change collation by table?

3) Which collation of Japanese should be used for best multibyte,
UTF-8 character sets? Currently we're testing with Japanese_CI_AS
(encoding MS932).

Any and all responses appreciated,
