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
