=head1 NOTES
As described in L<RDF::Trine::Node::Resource/as_ntriples>, serialization will
decode any L<punycode|http://www.ietf.org/rfc/rfc3492.txt> that is included in the IRI,
and serialize it using unicode codepoint escapes.
=head1 BUGS
Please report any bugs or feature requests to through the GitHub web interface
at L<https://github.com/kasei/perlrdf/issues>.
