99% of the time it's locale independant. I don't follow this logic of 
"if we can't make it work for everyone then it should stay broken for 
everyone". Following the Unicode rules would fix uppercasing for 95% of 
those not using english. And for the 5% of those who have to deal with 
those asymmetric upper/lower case rules... well, they'd have to deal 
with it either way.
