It's actually a problem with grub_strcasecmp since it doesn't take
utf8 into account. HFS+ unlike HFS uses Unicode (UTF-16 normalisation
form d to be exact) so no need for special handling here. Improving
strcasecmp is possible and may even be compact. Even if unicode counts
a lot of alphabets only few are bicameral. AFAIK main ones are Latin,
Greek, Cyrillic and Armenian. I hope that in most cases the lowercase
conversion can be done with some simple arithmetic operations
