That does not fully reflect the preferences of the staffs and end users.
Uppercased ones help people to recogize them more fast.
WIPO always come with uppercase one in all newspapers ever i'd read.
It's very natural for applications 
to respect its uppercase forms that end users perfer and type in.

I heard that nameprep is for enforcing uniqueness, but only for
input convenience. There are so many equivlances that are too complex
to be solved in nameprep.
