Can't select/inserting/updating some Chinese Character.

[Leung Data]

Dear All
I'm facing a problem:
When selecting/inserting/updating record in mySQL, some Chinese words couldn't be selected/stored correctly. As when encoding Chinese in the mySQL server, some byte will contains "|" (ie. reserve as "or" in the mySQL server) or "\" (ie. reserve as reference in the mySQL server, same as ' in the MSSQL server).

for example: 誠 will be encoded as Õ\
運 will be encoded as ß\
鋅 will be encoded as ä\

It seems mySQL server not cater multi-byte character currently.

And I'm looking for selecting / inserting / updating simplified character & trad character
record. And I had been complie the MySQL server with gb / big5 / utf8 already .

Hope anyone can get some help on me .

Thanks .
