The trick is to specify sorting with "-f" for the first column
and "-V" for the second.  Then it does what you seem to want:

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

    A 9
    A 10
    e 9
    E 9
    e 10
    E 10
    é 9
    é 10
    f 9
    F 10

There are several examples showing how to use sort in the
documentation.  Run "info coreutils sort" to display it,
or find it on-line:
