Oops.  I meant to say that sprintf silently skips any operand being formatted
under %s when that operand is not well-formed UTF-8.

[Bug localedata/16298] New: sprintf %s in a UTF-locale skips over invalid UTF-8

            Bug ID: 16298
           Summary: sprintf %s in a UTF-locale skips over invalid UTF-8
           Product: glibc
           Version: 2.17
            Status: NEW
          Severity: normal
          Priority: P2
         Component: localedata
          Assignee: unassigned at sourceware dot org
          Reporter: khw at cpan dot org
                CC: libc-locales at sourceware dot org

sprintf silently skips any operand being formatted with %s when the underlying
locale is UTF-8.  Not all strings have to be UTF-8 in such a locale, so this
behavior is unwarranted.  Even if it were, a UNICODE REPLACEMENT CHARACTER
should be output instead of silently skipping.  Some more details are at

Please produce a minimal test case demonstrating the problem; otherwise this
should be marked as invalid. A similar problem USED TO exist for %s format
specifiers with a precision specified (e.g. %.10s) but it was fixed sometime in
the past 2 years. I have never heard of such a problem existing with plain %s
and I suspect the perl commit message you linked to is just wrong.
