Hear me: regardless of the encoding used, case folding is 
locale-dependent. It doesn't matter a bit whether the OS uses Unicode or 
not.

Not at all. I merely pointed out that this sort of case-only rename must 
work without resorting to any kind of case-insensitive comparison. In 
order to get anything done, we first need a reliable algorithm that will 
work with this constraint.

You wouldn't notice the conflict until you commit, anyway.
