My real intent is to read from a file, and that's where I first noticed the problem. I made the script above to test and illustrate the problem. You said you're assuming that my script source file is UTF-8 encoded, and yes, that's the case.

Following is a tiny script which reads from a file and which has the same problem: 

#!/usr/bin/perl5.16.3                                                 
+                                           

use strict;
use HTML::Entities;

binmode STDIN, ':encoding(UTF-8)';
binmode STDOUT, ':encoding(UTF-8)';

while(<>) {
    utf8::decode($_);
    chomp;

    $_ = decode_entities($_);
    $_ = lc($_);

    print $_, "\n";
}

Here are the contents of my test input file: 

Édition limitée.
&Eacute;dition limitée.

&Eacute; still ends up as É, not é as intended. I think I'm doing what I'm supposed to do in terms of enabling the UTF-8 flag on $_, but please let me know if I've missed something.
