I am using the PostgreSQL driver version 7.03.02.00 and Postgresal database 7.4.6 running on Red Hat Linux 9.0. I am using the postgresql driver from my C# code and using ado.net inserts and retrieves the data from the database. The problem that I am facing is if I try to insert chinese characters from my front end the data is getting saved as a series of ???? instead of the actual chinese data. Can any one help me in solving this problem.
