Hi all, Ted told me about some bugs that the ext4 Unicode casefolding code has suffered over the past year -- they tried stripping out zero width joiner (ZWJ) codepoints to try to eliminate casefolded lookup comparison issues, but doing so corrupts compound emoji handling in filenames. This short series amends the Unicode testing in generic/453 and 454 to examine these compound emoji. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. This has been running on the djcloud for months with no problems. Enjoy! Comments and questions are, as always, welcome. --D xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=scrub-emoji-fixes fstests git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfstests-dev.git/log/?h=scrub-emoji-fixes --- Commits in this patchset: * generic/45[34]: add colored emoji variants to unicode tests --- tests/generic/453 | 55 +++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/generic/454 | 55 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 110 insertions(+)
