- SCT looks for efi_unicode_collation_protocol with an (old?) guid, {0x1d85cd7f, 0xf43d, 0x11d2, 0x9a, 0x0c, 0x00, 0x90, 0x27, 0x3f, 0xc1, 0x4d)
- SCT uses a hard-coded language name, "eng," in SctInializeLib()
These assumptions conflict with Heinrich's current unicode implementation.
While this patch fixes them in a quick way, it's more of an informative one so that we will share and discuss them.
FWIW the collation protocol v1 is considered deprecated pretty much since UEFI - and same goes for the "eng" name which is the v1 representation of "English".
I had a similar patch in my queue, but after consultation with Heinrich we agreed that we should be a clean UEFI implementation without too much legacy. What the goal instead should be is to help the UEFI people to fix SCT to no longer require deprecated protocols.
I've thus added Vincent and Dong for input :).
Thanks,
Alex
