Index vs. preferred name can get a bit wonky. I used to work on software that had a lot of attendee/speaker list functionality. Different types of customer had strong expectations about how names should be displayed and ordered, sometimes even in different contexts (attendees might be listed by last name but speakers by first, etc.). We had medical conferences where everybody would be listed as "Dr. Fredrica Bloggs, MD" but the sort order would be by last name. And that was just for English-speaking customers.

it is really something to be dealt with via locale settings but the lack of standardized data underlying what the locale logic would display really throws a wrench in things
