LDAP sorting result with accents

Hi,

The sorting of LDAP result with accent is not working as expected:

What we get:
Mutten Robert
Myles Tristan
Müller Steve

As you can see, letters with accent are sorted after the z which is not correct.

What we expect:
Müller Steve
Mutten Robert
Myles Tristan

Is there a way to correct it please?

Regards.
