we should, of course, continue to use the one we always used (for "ascii", there is no difference between the two). +1 This seems the most (only ?) logical solution. No; always considering Unicode and non-ASCII byte strings to be distinct is just as logical. Except there has been an implicit promise in Python for years now that ascii byte-strings will compare equally to the unicode equivalent: lots of code assumes this. Breaking this is fine in principle - but for Py3K not Py 2.x.
That means Martin's solution is the best for the current problem. (IMHO of course...)
