The UEFI specification does not specify if the characters that have to be replaced by underscore in function StrToFat() of the Unicode collation protocol are those forbidden in FAT long names or those in FAT short names. EDK2 and UEFI SCT assume it is those forbidden in FAT 8.3 short names.
Adjust the list of forbidden characters.
