The standard allows negative return values only for encoding errors. So
for typical systems (i.e. sizeof(char) < sizeof(int), wchar_t is Unicode
code points), a %c with an argument outside the range of char should
work. Or a %lc with an argument that is not a Unicode code point. Or a
%ls with an argument that is an array containing values that are not
valid Unicode code points.
