[Python-3000] Support for PEP 3131

[Pierre Hanser]

hello

i would like to add that even for a french user, it would be good
to have the possibility to use non ascii identifiers.

take the simple problem of the difference between "action to do"
and "action done".

In english, most of the time, adding 'ed' to the verb will do
the difference: change -> changed

great, this is still ascii!

in french:   change -> changé   (ends with 'eacute')

bad, not ascii!

The possibility to use non ascii characters for identifiers
would be a strong bonus in my opinion.
