        # Perl example using Unicode and regex
        use strict;
        use warnings;
        use utf8;

        my $string = "Héllo, 世界";
        
        # Match Unicode characters
        if ($string =~ /[\x{00E9}\x{4E16}\x{754C}]/) {
            print "Found a Unicode character!\n";
        } else {
            print "No Unicode character found.\n";
        }
