in mysql server instance configuration

instead of selecting standard character set, select best support for multilingualism or manual selectd default character set / collation

Thanks for response.
In Java, String are stored as UTF16, not UTF8. But how MySQL knows which charset/collation EJB(client to DB) is using if I config MySQL only? For MySQL I can config DB and Server charset/collation, but not client connection/results charset. Thanks for helping me understand.
