Convert on uppercase unaccentent unicode character

[JBJ]

Hi,
I'am very newbie in Python.
For the moment I'am trying to convert an unicode character to his uppercase
unaccented character.
By example with locale fr_FR:
a,A,à,À should return A
o,O,ô,Ô should return O
œ,Œ should return Œ
i,I,î,Î should return I
 
Have you some suggestions ?

Thank.
