Hey Rick,
Unicode stuff doesn't work well in psycopg1 either. I'm all for not
supporting it anymore, as making the mistake of starting off in it cost me a
few days tracking down strange problems.
It's documented in the wiki and in the mailing list, but I agree there's no
good reason (besides version confusion) to use psycopg1 vs psycopg2.
