New submission from Lennart Regebro <rege...@gmail.com>:
If we return unicode, SpoofOut's buf variable becomes automagically converted
to unicode. This means all subsequent output becomes converted to unicode, and
if the output contains non-ascii characters that fails.
That means that
>>> print u'\xe9'.encode('utf-8')
é
Will work just fine, but
>>> print u'abc'
abc
>>> print u'\xe9'.encode('utf-8')
é
Will fail.
The reason for this is that when "resetting" the doctest output only a
truncate(0) is done, so the buf variable will continue to be unicode. I include
tests + a patch that will set self.buf to '' if empty when trunkated. Other
options are also possible, like changing the .truncate(0) to a .buf = '' but
that's ugly, or adding a reset() method on SpoofOUt.
