I'm trying to capture the upper, lower, left, and right arrow keys using the code below. 
#!/usr/bin/perl

use strict;
use Term::ReadKey;

ReadMode( 'cbreak' );
while (1) {
    my $char = ReadKey( 0 );
    print "Character: $char\n";
}

ReadMode( 'normal' );

Please see below when I run this code, 
When I type 'c', I get this which is okay.
Character: c

When I hit 'the upper arrow', I get this output. 
Character: 
Character: [
Character: A

Can anyone explain this? Or how do I capture the arrow keys?
