Module produce UC2 on top of UC.
|
|
|
|
UEFI 2.1 specification supersedes Inte's EFI Specification 1.10.
|
|
EFI_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 UC2 on top of UC. This module is used on platform when both of
|
|
these two conditions are true:
|
|
1) EFI 1.10 module producing UC present
|
|
2) And the rest of modules on the platform consume UC2
