I see two things here:
1. some characters may only have a lower case form, so converting
to upper case is not posssible. Example: German <ss>, Greenlandic <kra>.
2. a number of lower case forms exists where there is only one upper
case form, example Greek sigma, where there is a terminal sigma.
In the first instance I can see a reason to normalize on lower-case,
but in the second case I see problems in chosing which lower case
to normalize on.
I would rather that you did not normalize, but made a case-independent,
or case-and-accent-independent comparison, for example using
the functions and tables of the forthcoming ISO sorting standard
