I recently came across with a related problem and have two questions
(unresolved until now):

1.
Using sort, reading the man page of it, it should be sufficient to
set LC_COLLATE correctly. It seems that setting LANG (or unsetting it)
changes the sort Order, why?

2.
Speaking about German Umlauts, should they be treated as their normal
letters, i.e. 'ä' is like 'a', as one can read in Wiki, or how they are
sorted exactly?
