I've since this post changed my mind, and think it should only warn if
there are wide characters after attempting to downgrade first. Just like
the existing "wide character in %s" warning.
juerd@lanova:~$ perl -wle'$a = "foo\x{ff}"; utf8::upgrade($a); print $a' | hexdump -C
00000000 66 6f 6f ff 0a |foo..|

juerd@lanova:~$ perl -wle'$a = "foo\x{20ac}"; utf8::upgrade($a); print $a' | hexdump -C
Wide character in print at -e line 1.
