I should clarify that the functions I'm referring to here in a)-f) are
alternatives for the function that is used by applications to test
equivalence of valid encoded names. In the case of g), unnormalised names
are not valid, so it is sufficient to use ASCII case folding to test
equivalence.

Actually a) and b) define the same function, so they should be considered
as a single alternative; call it ab).
