In 2.1, yes.

=46or as long as we have text data stored in a mix of string and unicode
objects, this rule is a good way of picking up encoding-assumption
bugs early.

(for 2.0 I argued against this, but today I can recognise its
usefulness)

Of course, this should work once type(u"abc")=3D=3Dtype("\245"). I think
we agree this is the long term goal.

A small variation:

>>> x =3D 'd'
>>> print u"abc"+x
abcd
>>> x =3D "\245"
>>> print u"abc"+x
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
UnicodeError: ASCII decoding error: ordinal not in range(128)
