This patchset implements the EFI_UNICODE_COLLATION_PROTOCOL and provides unit tests.
Additionally some errors when handling Unicode strings are fixed. * possible stack overflow * incorrect handling of precision attribute in printf() * incorrect limit on variable length
Some old Unicode functions are replaced.
An error in Unicode handling in the FAT file system shall be fixed after merging Takahiro's FAT patches. Until then some redundancy between old and new Unicode functions remains.
v2: use CONFIG_IS_ENABLED(EFI_LOADER) instead of defined(CONFIG_EFI_LOADER) && !defined(CONFIG_SPL_BUILD) add configuration option EFI_UNICODE_CAPITALIZATION use ut_assert*() for testing test illegal Unicode sequences add more comments
