Normally not but fat code passes short filenames to grub without any
encoding conversion. In other words fat code assumes short filenames
are in utf8. A problem in both hfs and fat is that it uses local
encoding and at least in case of fat it's impossible to know which one
from filesystem alone. We would need something like mount option to
get this right. It could be sth like
hd0_0_codepage=437

I agree with you. I see no reason for users to have unicode characters
in kernel names. And so getting it right is too much work for an
almost zero benefit
