Most annoying thing about ‘å’. Danes adopted it as a replacement for the digraph ‘aa’, to distance themselves from Germans. And slapped it at the end of the alphabet. But later dropped its use, since they were habituated to ‘aa’ anyway. So now ‘Aarhus’, where ‘aa’ technically stands in for ‘å’, must be sorted at the end of a list, but ‘aardvark’ at the beginning.
