Perl: Unicode Tutorial 🐪

Unicode Encoded Perl Source Code

If your Perl script is encoded in UTF-8 , then you need to declare it, like this:

use utf8;

for processing unicode string, you need at least perl 5.14, released in 2011.

use v5.14;

use strict;
use utf8;

# processing Unicode string
my $xx = 'I ★ you';
$xx =~ s/★/♥/;
print "$xx\n";
# I ♥ you

Set Input Output Etc to Unicode

run perl with perl -C
