NAME Q and Aperlunitut isn't really a Unicode tutorial, is it? What character encodings does Perl support? Which version of perl should I use? What about binary data, like images? When should I decode or encode? What if I don't decode? What if I don't encode? Is there a way to automatically decode or encode? What if I don't know which encoding was used? Can I use Unicode in my Perl sources? Data::Dumper doesn't restore the UTF8 flag; is it broken? Why do regex character classes sometimes match
