ASCII codec encoding error

[gworley3]

I'm seeing the following error when trying to select from one of my foreign tables (we have data stored in UTF-8):

postgres=# select * from remote_companies limit 1;
ERROR:  Error in python: UnicodeEncodeError
DETAIL:  'ascii' codec can't encode character u'\xe4' in position 69: ordinal not in range(128)

I already tried switching Postgres to UTF8 (recreated the database to use UTF8 encoding and en_US.UTF8 locale and made sure client_encoding is set to UTF8) but didn't resolve it, so seems to be happening in the Python code.
