Users\ncurrently depending on the <code>punycode</code> module should switch to using the\nuserland-provided <a href=\"https://github.com/bestiejs/punycode.js\">Punycode.js</a> module instead. For punycode-based URL\nencoding, see <a href=\"url.html#url_url_domaintoascii_domain\"><code>url.domainToASCII</code></a> or, more generally, the\n<a href=\"url.html#url_the_whatwg_url_api\">WHATWG URL API</a>.</p>\n<p>The <code>punycode</code> module is a bundled version of the <a href=\"https://github.com/bestiejs/punycode.js\">Punycode.js</a> module. It\ncan be accessed using:</p>\n<pre><code class=\"language-js\">const punycode = require('punycode');\n</code></pre>\n<p><a href=\"https://tools.ietf.org/html/rfc3492\">Punycode</a> is a character encoding scheme defined by RFC 3492 that is\nprimarily intended for use in Internationalized Domain Names. Because host\nnames in URLs are limited to ASCII characters only, Domain Names that contain\nnon-ASCII characters must be converted into ASCII using the Punycode scheme.\nFor instance, the Japanese character that translates into the English word,\n<code>'example'</code> is <code>'例'</code>. The Internationalized Domain Name, <code>'例.com'</code> (equivalent\nto <code>'example.com'</code>) is represented by Punycode as the ASCII string\n<code>'xn--fsq.com'</code>.</p>\n<p>The <code>punycode</code> module provides a simple implementation of the Punycode standard.</p>\n<p>The <code>punycode</code> module is a third-party dependency used by Node.js and\nmade available to developers as a convenience. Fixes or other modifications to\nthe module must be directed to the <a href=\"https://github.com/bestiejs/punycode.js\">Punycode.js</a> project.</p>",
