[Python-ideas] Add Unicode-aware str.reverse() function?

[Paddy3118]

Thanks for your replies.

After reading them,, although I seem to have a brain freeze at the moment 
and 
cannot think of an algorithm; I think it plausible, just in the ASCII world 
for 
someone to want to iterate through characters in a string in reverse order 
- 
maybe to zip with another existing iterable that would otherwise need to be 
reversed? If it shifted from ASCII to unicode then letters with their 
combining
characters would have to be reversed as a single character; but also 
iterated 
over as a single unicode "character" - another problem!

I thought so, I scratch the surface of unicode, and find a deep chasm 
awaits.
