sorting of contact list

[donald]

Currently, when the contact list is sorted by family name, but lower-case names ("von ...", "van ...") and ames with Umlaute ("Ö...") are shown after the usual names ("A...", "Z...").

Should we use case-blind compare? Or something special with "von", "van" etc. ?

Should "Ö" be sorted as "Oe" ? Or should the collation sequence depend on the current language setting?

I don't know how this is handled usually (aren't there maybe some norms and best-practices?) but my gut feeling tells me we should treat umlauts ä, ö, ü as letters a, o, u, respectively. The same with ø, é, å or modified consonants like ç, ł or č – we could convert them to some sort of "canonical ASCII". But as I said, I don't know if this acceptable, but this is the behaviour I would expect.
