This is better, but still not perfect: "é 9" should be
before "e 10", like "E 9" is before "e 10", as in a
dictionnary, where "éa" is before "eb". That means that
e=E=é=è=É=È if something after makes a différence.

Look at this example:

echo "
é 9
e 10
éa
eb
E 9" | sort -k1,1f -k2,2V

E 9
e 10
é 9
éa
eb

"E 9" is correctly moved on first place, but the placement of
"é 9" doesn't follow the same law.

I probably can do with that "unperfect" order, because such
situation are not frequent in real life, but if there's a
solution, I'd be happy to know it.

This is nice, because I had misunderstood the usage of -k by
reading the man page.
