Should UNICODE() then get a third, optional, keyword argument using
which you can, if you want to, pass in an encoding ? In case you don't
and it being the default None psycopg2 will still try getting it from
cursor.connection:

   def UNICODE(value, cursor, encoding=None):

      if encoding is None:
         encoding = cursor.connection.encoding

      ...

Agreed, the use case is rather slim.
