> it should be using to_utf8 instead, right?

Likely yes.  Python does not mix utf8 and unicode well.  Possible solutions
are:

a) Whenever some API returns python unicode object, convert it to utf8 and
pretend unicode does not exist.

b) Convert everything to unicode.  'yum' uses this.

to_utf8 and to_unicode are wrappers that skip conversion if already done.

c) sys.setdefaultencoding('utf-8')

Python then understands utf8 when implicitly converting strings to unicode, so 
'unicode + utf8' works as expected.  It's effectively b) but without the need
to call to_unicode explicitly.  It has issues too.

If most of the code expects utf8, using a) is probably best.
