  "description": "Net::Whois::Raw versions before 2.99044 for Perl ship a pwhois command-line tool that queries WHOIS for the wrong domain for unicode domain names.  pwhois encodes each non-ASCII label directly using Net::IDN::Punycode and prepends xn--. Apart from lowercasing ASCII and Cyrillic letters, it skips the IDNA mapping and normalization steps, so a label with other uppercase letters, or not in NFC, encodes to a different A-label than its IDNA form. For example, a label of U\u002B00C9 followed by \u0022cole\u0022 encodes to \u0022xn--cole-pka\u0022 rather than \u0022xn--cole-9oa\u0022.  The Net::Whois::Raw library modules are not affected.",
