Follow-up Comment #3, bug #52890 (project findutils):
You've discovered a fundamental flaw in the specification of the glob()
function - it is only required to have well-defined behavior on byte strings
that are valid encodings in the current locale. There is no portable way to
make glob patterns match file names that contain encoding errors in a
multibyte locale. But what you CAN do is specify 'LC_ALL=C find' for any
situation where you want to ensure that globs cannot fail due to encoding
errors, because the C locale is guaranteed by POSIX to be a single-byte
8-bit-clean locale (thus, no encoding errors are possible in that locale, and
glob() no longer has to worry about failure to match a byte string that is not
a valid character string).
