In german, an Umlaut (äöü, ÄÖÜ) is a different letter than the
normal character without the dots (aou, AOU).
WRT sorting: there are two different sorting possibilities:
(1) In a well-known dictionary (Duden), a and ä seems to be
considered equivalent for sorting, e.g.
Mahraun < Mähre < Mähren < Mahrenholz.
(2) In telephone books an Umlaut is considered equivalent(?)[1]
to the normal vocal + "e" (ä == äe, Ü == UE, etc.), e.g.
Modul < Möbel < Möller <= Moeller < Mof... .
[1] In fact, I can't even tell if "oe" == "ö" or if there is an order,
if everything else is equal.
Neat, isn't it?
