This works as expected (this is on an ASCII terminal):
>>> unicode('asdf\xff', errors='replace')
u'asdf\ufffd'
This does not work as I expect it to:
>>> class C:
... def __str__(self):
... return 'asdf\xff'
...
>>> o = C()
>>> unicode(o, errors='replace')
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: coercing to Unicode: need string or buffer, instance found
Shouldn't it work the same as calling unicode(str(self), errors='replace')?
It doesn't matter what value you use for 'errors' (ignore, replace, strict);
you'll get the same TypeError.
What am I doing wrong? Is this a bug in Python?
