Disallow non-ASCII and ASCII control characters in FAT label 

FAT label is interpreted according to current OEM DOS codepage which is
system dependent setting. But most DOS codepages have same characters in
printable ASCII range, so this is the only safe range of characters which
are interpreted in same way by most programs and operating systems. Also
all DOS codepages are only 8bit, so characters above U+FF cannot be stored
to FAT label.
