One can discuss if the algorithm is correct or not, but that algorithm
is defined in UNICODE 1.1, i.e. both decomposition rules and how to
do case-independent matches.

Note that I am not claiming that it is correct - any of the two lagorithms,
but the good thing is that we have _one_ definition and that is what is
needed in this case.
