java - DB2 database using unicode -

I have a problem with the DB2 database which should contain Unicode characters. The connection is established using JDBC. INSERT (1, N 'N') values ​​in my_table (id, string_field) values, what do I have to do if I want to insert a Unicode string into the database? My unicode string '); INSERT (1, 'my unicode string') in

or

  my_table (id, string_field) values;  

I do not know whether to use N-prefix or not for most databases there works great when using it but I am not quite sure about DB2 . I also have a problem that I do not have a DB2 database where I can test these statements. :-(

Thank you very much!
