how do I create a db with unicode encoding on a utf8 server

I have a Postgre server with UTF8 as the default encoding. I am trying to create a new database on this same server  with UNICODE encoding so that I can load an UNICODE database from another server. No matter how I specify unicode option on this utf8 server, it just  created a utf8 db for me any way. Can different databases have different encodings on the same server? I remember they could before....

Thanks,
Jessica
