How does semantic versioning quirks in Perl interact with Unicode and encodings?

        # Example of semantic versioning in Perl with Unicode handling
        use strict;
        use warnings;
        use utf8;

        # Versioning following the semantic versioning rules
        my $version = '1.0.0';  # MAJOR.MINOR.PATCH

        # Example of handling Unicode in a string
        my $string = "Hello, 世界"; # "Hello, World" in Chinese

        # Print version and string
        print "Current version: $version\n";
        print "Greeting: $string\n";
