>>> from cStringIO import StringIO
>>> f =3D StringIO()
>>> f.write(u'foo')
>>> f.write(u'bar')
>>> f.getvalue()
'foobar'

versus

>>> from StringIO import StringIO
>>> f =3D StringIO()
>>> f.write(u'foo')
>>> f.write(u'bar')
>>> f.getvalue()
u'foobar'

i.e. cStringIO tries to make everything into 8 bit strings. Apparently
(I just tested) it tries to get a str() upon input:

>>> from cStringIO import StringIO
>>> f =3D StringIO()
>>> f.write(u'foo=EB')

will get you an ASCII encoding error.
