        # Example of argument passing and Unicode handling in Perl
        use strict;
        use warnings;
        use utf8;

        sub greet {
            my ($name) = @_;
            print "Hello, $name!\n";
        }

        my $utf8_name = "世界"; # UTF-8 encoded string
        greet($utf8_name);
