In my opinion no. As far as String is concerned, since it is simply 
[Char], it should be considered as simply a list of codepoints without 
further interpretation. So 'length' and its instance for Eq should be the 
same as for any other list.

Consider the latter as two codepoints, and don't worry about characters. 
There should be separate functions for doing such things as decomposition 
and equivalence.
