> PEP: 349
> Title: Generalised String Coercion
...
> Rationale
>    Python has had a Unicode string type for some time now but use of
>    it is not yet widespread.  There is a large amount of Python code

>    The long term plan for Python is to phase out the str type and use

This PEP strikes me as premature, as putting the toy wagon before the 
horse, since it is premised on a major change to Python, possibly the most 
disruptive and controversial ever, being a done deal.  However there is, as 
far as I could find no PEP on Making Strings be Unicode, let alone a 
discussed, debated, and finalized PEP on the subject.

>   Clearly, a smooth migration path must be provided.

Of course.  But the path depends on the detailed final target, which has 
not, as far as I know, has been finalized, and certainly not in the needed 
PEP.  Your proposal might be part of the transition section of such a PEP 
or of a separate migration path PEP.
