It is not enough just to say use utf8;. Your source file must actually be in utf-8 rather than some other encoding. When I download your sample and try to run it, I get the same compile errors you do. But when I edit it with vim and issue the vim :set fileencoding? command, it says fileencoding=latin1. When I :set fileencoding=utf-8 and save the file, the compile errors go away.

As kcott pointed out, you will also need to correct your use IO ... to get the output you want.
