in thread CPAN's URI.pm versus Japanese as Unicode?

Thanks, though adding use utf8 does not affect the result perhaps I need to convert from Punycode. Is there a module for converting from Punycode to Unicode? Working with the host names as Punycode is not really an option, as far as a I can tell, because the host name needs to remain human-readable.

The goal is to extract the host name from the URI and the host name happens to be Japanese as Unicode, as is wont to happen.

    Yes, it does.

    Corion already pointed you to Net::IDN::Encode as one possibility.

    use warnings;
use strict;
use utf8;
use open qw/:std :encoding(UTF-8)/;
use URI;
use Net::IDN::Encode qw/domain_to_unicode/;

my $href="https://マリウス.com/";
my $uri = URI->new($href);
my $domain = domain_to_unicode($uri->host);
print $domain,"\n";  # prints "マリウス.com"
