Save unicode characters in DB using java

Question

I need to save some uni-code characters in Sql server 2005 DB with JDBC, When i try to save "O’CON" into DB column having type NVarchar using a stored procedure it saves "O?CON" `(where ’ character is not `` or ')

I did some R&D and found that i need to add useUnicode=true&characterEncoding=UTF-8 some where in my DBcon.properties file that contains all the details of DB connection,

Can some one help me out where to add this into properties file or it i can add it at run time when i create a connection object.

Or if someone can help me how to save unicodes characters in DB using java.

Thanks.

To connect to database you use connect string specific to your database and driver.

I used MS MSQ long time ago but I remember that they had jtds driver. Connect string for such driver looks like:

jdbc:jtds:sqlserver://hostname:1433/my_database;useUnicode=true;characterEncoding=UTF-8

But from that time MS create their own JDBC driver and if you use it then I think you can add:

sendStringParametersAsUnicode=true

to your connect string. It is decribed at http://technet.microsoft.com/en-us/library/ms378988.aspx

In a case of problems show us your connect string and code where it is used.
