Sorting umlauts characters Ä, Ö, Ü

[diogoalves]

In German letters with umlaut (Ä, Ö, Ü) are treated generally just like their non-umlauted versions; ß is always sorted as ss. This makes the alphabetic order Arg, Ärgerlich, Arm, Assistent, Aßlar, Assoziation. For phone directories and similar lists of names, the umlauts are to be collated like the letter combinations "ae", "oe", "ue". This makes the alphabetic order Udet, Übelacker, Uell, Ülle, Ueve, Üxküll, Uffenbach.

it could be done replacing Ä, Ö, Ü by A, O, U .

but I am not sure where to write this in code.

For now, you should check out sugar.js.

I just wanted to note that strings containing umlauts are handled differently from others by this module.

Strings with umlauts are handled by localeCaseCompare, strings without are simply passed to <. This leads to very mixed results.
