But would that be different from the number of characters?  

My confusion comes from his assertion that Python itself does not need to
care whether it's raw string or unicode.   Is there any need for the
interpreter to split an identifier into sequence of characters?  If the
answer is no, then I guess my question is moot.

My question was about what would be the case under the proposals.  But I
guess I'm way out of my domain here.
