/** @file
Module produce UC on top of UC2.

UEFI 2.1 specification supersedes Inte's EFI Specification 1.10.
UNICODE_COLLATION_PROTOCOL defined in Inte's EFI Specification 1.10 is replaced by
EFI_UNICODE_COLLATION_PROTOCOL in UEFI 2.1.
This module produces UC on top of UC2. This module is used on platform when both of
these two conditions are true:
1) EFI 1.10 module consuming UC present
2) And the rest of modules on the platform produce UC2
