Actually, I did (see my comments on sf): In a Unicode string, escape
processing of, say, u"\=F6" works incorrectly in your implementation,
and in a plain string, processing is incorrect if you have an encoding
which uses '\' as the second byte.

The rationale is different: people where proposing that all string
literals should be Unicode strings - then the question is how to
denote byte strings.
