Does case folding in the kernel pass the Turkey test? I.e., are different locales taken into account in order for the correct string to be matched? As far as I remember this was a big deal for supporting Unicode on case insensitive filesystems, because it than means that a file stops existing depending on the current locale. For instance, take a file named "ivory.txt": `stat("IVORY.TXT")` on a case-insensitive filesystem would succeed if the locale is en_US but fail on tr_TR due to the uppercase version of 'i' being 'İ' there instead.
