error with unicode thing??

Hi all,

I have created a table
create table temp1(a varchar(200));

and then I tried running the following code.

String msg1 = "\u0000abcd";
PreparedStatement preparedStmt =pgConnection.prepareStatement("insert
into temp1 values(?)");
preparedStmt.clearParameters();
preparedStmt.setString(1, msg1);
preparedStmt.executeUpdate();
preparedStmt.close();

And it throws an Exception saying "\0 not allowd"what should I do ? 
How should I insert unicode string using jdbc ?
