My digging let me to belive that toupper()/tolower()/sorting is 
intentionaly left out since each locale has its own rules. IIRC the 
example given is 'ä' that in german is sorted together with 'a' but in swedish 
sorted as its own character.

So the only solution is to use "wchar.h", and note that wchar is 
UTF-16 on Windows and UTF-32 on most unices.
