I don't see anything that indicates that the returned object is the
empty string. Simply because there is no code testing for that. And of
course you don't show any debugging output, which doesn't help either.

What is that? IPython? And I don't see no empty string here. *What* I
see is the way python's interactive prompt puts out strings, like this:
>>> unicode("foo")
u'foo'
Do you mean by any chance that you don't understand why print prints
foo, but the prompt shows u"foo"? That is because the prompt invokes
repr(o)
to print out an object:
>>> print repr(unicode("foo"))
u'foo'
Which means that the output includes quotes and the "u"-prefix in case
of an unicode object to help the user to see what the current object
looks like.
