Great!

Al, could you please take this patch series?

I was thinking about it, but it needs more refactoring. Currently
exfat_toupper() is used on other places for UTF-16 (u16 array) and
therefore it cannot be extended to take more then 16 bit value.

But I agree that this is another step which can be improved.
