GCC accepts the following with -ansi -pedantic -Wall without diagnostics
#include <stdlib.h>
wchar_t z[] = L"a" "\xff";
GCC claims a default execution charset of UTF-8; presumably the default
execution wide character set is UTF-32. But "\xff" is a two-character narrow
execution character set string literal, with characters \xff \0, which is
invalid UTF-8 and so cannot be converted in a meaningful way to the execution
character set (whatever it is).
I would expect the above code to be rejected, or at least diagnosed.
