EFI support when it started was about 10kb. I assume it grew by now, so maybe we're at 15kb by now. Adding another 4kb for the upper/lower translation is *massive* by comparison. Edk2 only supports upper/lower conversion for English anyway, so we're not worse off if we don't support all the fancy unicode conversions.
