For opening, this is is necessary for backward compatibility. For /creation/, we could certainly mandate UTF-8 for the addition of new files, which is why I qualified with O_CREAT. The same would apply for other syscalls which create file paths (e.g. mknod, mkdir, bind). This would permit UTF-8 to be enforced going forward while retaining a means for users to migrate broken naming to UTF-8. Which locales don't currently have charsets mapping to Unicode? Could we remove the non-UTF-8 locales which /do/ have complete UTF-8 coverage and replace them with aliases? That would at least achieve the transition for the vast majority of locales.
