NAME

Net::LibIDN - Perl 6 bindings for GNU LibIDN

SYNOPSIS

use Net::LibIDN;

my $idna := Net::LibIDN.new;

my $domain := "m\xFC\xDFli.de";
my Int $code;
my $ace := $idna.to_ascii_8z($domain, 0, $code);
say "$ace $code"; # xn--mssli-kva.de 0

my $domain2 := $idna.to_unicode_8z8z($domain, 0, $code);
say "$domain2 $code"; # müssli.de 0

DESCRIPTION

Net::LibIDN is a wrapper for the GNU LibIDN library. It provides bindings for its IDNA, Punycode, stringprep, and TLD functions. See Net::LibIDN::Punycode, Net::LibIDN::StringPrep, and Net::LibIDN::TLD for more documentation.

METHODS

Converts a UTF8 encoded string $input to ASCII and returns the output. $code, if provided, is assigned to IDNA_SUCCESS on success, or another error code otherwise.

Converts an ACE encoded domain name $input to UTF8 and returns the output. $code, if provided, is assigned to IDNA_SUCCESS on success, or another error code otherwise.

CONSTANTS

String containing the official IDNA prefix, "xn--".

FLAGS

Allow unassigned Unicode codepoints.

Check output to ensure it is a STD3 conforming hostname.

ERRORS

Successful operation.

Error during punycode operation.

IDNA_USE_STD3_ASCII_RULES flag was passed, but the given string contained non-LDH ASCII characters.
