Isn't this warranted by section "LC_COLLATE Category in the POSIX Locale" in
<https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap07.html> ?

UTF-8 has the nice property that byte-per-byte comparison and codepoint-per-
codepoint comparison are equivalent. If the encoding was not UTF-8, but
e.g. GB18030, I would agree that there is a problem. But there is no C
locale with GB18030 encoding on any platform.
