CharacterSet option with MSSQLServerDatabase

Hi all,
I can set the CharacterSet option to connect to an ODBCDatabase by using this syntax of the connectionstring:
Dim dbobj as ODBCDatabase
dboj = new ODBCDatabase
dboj.DataSource=“Driver={SQL Server Native Client 11.0};Server=serveraddress;WSID=serveraddress;Database=dbname;UID=user;PWD=password;CharacterSet=UTF-8

How can I set this option when using a MSSQLServerDatabase object?

TIA
