# Example of dereferencing with Unicode handling in Perl my $unicode_string = "Hello, 世界"; # UTF-8 encoded string my $array_ref = [ qw( One 二 Three ) ]; # Array reference with mixed encodings my $hash_ref = { 'key' => "値", 'value' => $unicode_string }; # Hash reference with Unicode # Dereferencing the array reference foreach my $item (@$array_ref) { print "$item\n"; # Handles Unicode correctly } # Accessing values from the hash reference print $hash_ref->{'key'}; # Prints the value in UTF-8
