Unicode_Collation Protocol - Intel Extensible Firmware Interface Specification

This chapter defines the Unicode Collation protocol. This protocol is used to allow code running in
the boot services environment to perform lexical comparison functions on Unicode strings for given
languages.

Unicode Collation Protocol
Performs a case-insensitive comparison of two Null-terminated
Unicode strings. See Section 13.1.1.
Performs a case-insensitive comparison between a Null-
terminated Unicode pattern string and a Null-terminated Unicode
string. The pattern string can use the '?' wildcard to match any
character, and the '*' wildcard to match any substring. See
Section 13.1.2.
Converts all the Unicode characters in a Null-terminated
Unicode string to lower case Unicode characters. See
Section 13.1.3.
