Apparently the problem is that "str" is a different type in Python than
"unicode".  I could get it to work this way:

create or replace function unaccent(text) returns text language plpythonu as $$
import unicodedata
rv = plpy.execute("select setting from pg_settings where name = 'server_encoding'");
encoding = rv[0]["setting"]
s = args[0].decode(encoding)
s = unicodedata.normalize("NFKD", s)
s = ''.join(c for c in s if ord(c) < 127)
return s
$$;

It works for me now.  Thanks to Euler for tracking the Python problem
down and to you for the commit!
