[Python-Dev] PEP 414 - Unicode Literals for Python 3

Your counter-example is non-ASCII characters/bytes. I doubt that this  
is a valid
use case; in a "native" string, these shouldn't occur (i.e. native  
strings should
always be ASCII), since the semantics of non-ASCII changes drastically between
2.x and 3.x. So whoever defines some API to take "native" strings  
can't have defined
a valid use of non-ASCII in that interface.

Indeed it should. If there is a known application of non-ASCII native strings,
I surely would like to know what that is.
