Accentuated characters aren't classified alphabetically in navigation lists

The accentuated characters seems to be classified at the end of the alphabet in navigation lists (artists, albums...). For instance, when I want to listen to Émilie Simon's work, I'm waiting to find her in the E part of the alphabet, but she appears at the end of the list.

All accentuated characters should be regarded as the non-accentuated corresponding letter.
