       Zonemaster::Engine::Normalization - utility functions for names normalization

SYNOPSIS

           use Zonemaster::Engine::Normalization;

           my ($errors, $final_domain) = normalize_name($domain);

EXPORTED FUNCTIONS

       normalize_label($label)
           Normalize a single label from a domain name.

           If the label is ASCII only, it is down cased, else it is converted according to
           IDNA2008.

           Downcasing of upper case non-ASCII characters, normalization to the Unicode NFC format
           and conversion from U-label to A-label is performed by libidn2 using "to_idn($name,
           ...)" in Zonemaster::LDNS.

           Returns a tuple "($errors: ArrayRef[Zonemaster::Engine::Normalization::Error],
           $alabel: String)".

           In case of errors, the returned label will be undefined. If the method succeeded an
           empty error array is returned.

       normalize_name($name)
           Normalize a domain name.

           The normalization process is detailed in the normalization document
           <https://github.com/zonemaster/zonemaster/blob/master/docs/specifications/tests/RequirementsAndNormalizationOfDomainNames.md>.

           Returns a tuple "($errors: ArrayRef[Zonemaster::Engine::Normalization::Error], $name:
           String)".

           In case of errors, the returned name will be undefined. If the method succeeded an
           empty error array is returned.
