I have generally stayed out of the UTF-8 versus ACE debate, but the above 
statement cannot go unpunished.  UTF-8 is a character encoding scheme for 
*every single code point* in ISO/IEC 10646.  That means every character, 
upper- and lower-case, in every script, has its own UTF-8 representation.

To say that UTF-8 does not preserve case distinctions is complete nonsense.  
It is the nameprep stage that folds away case distinctions (for better or 
worse).
