Your __str__ method is not returning a string. It's returning a
Unicode object. Under Python 2 (which you're obviously using, since
you use print as a statement), strings are bytes. The best thing to do
would be to move to Python 3.3, in which the default string type is
Unicode, and there's a separate 'bytes' type for communicating with
file systems and networks and such. But if that's not possible, I
would recommend having a separate method for returning a Unicode
string (the same as your current __str__ but with a different name),
and have __str__ call that and encode it - something like this:
def describe(self):
return u'msgid: "%s"\nmsgstr: "%s"' %(self.msgid, self.msgstr)
def __str__(self):
return self.describe().encode(self._encoding)
But it'd definitely be better to move to Python 3.
