This seems plainly wrong to me:

for my $word (@words) {
    my $result = $word =~ $pattern ? "matches" : "doesn't match";
    printf qq/The word "%s" %s the pattern %s\n/, $word, $result, $pat
+tern;
}

What's going on? Why is Perl complaining that, for example, "\x{009a} does not map to cp1252." It does map to cp1252 (Windows-1252 or ANSI).
