/**
 * **The version of the punycode module bundled in Node.js is being deprecated.**In a future major version of Node.js this module will be removed. Users
 * currently depending on the `punycode` module should switch to using the
 * userland-provided [Punycode.js](https://github.com/bestiejs/punycode.js) module instead. For punycode-based URL
 * encoding, see `url.domainToASCII` or, more generally, the `WHATWG URL API`.
 *
 * The `punycode` module is a bundled version of the [Punycode.js](https://github.com/bestiejs/punycode.js) module. It
 * can be accessed using:
 *
 * ```js
 * const punycode = require('punycode');
 * ```
 *
 * [Punycode](https://tools.ietf.org/html/rfc3492) is a character encoding scheme defined by RFC 3492 that is
 * primarily intended for use in Internationalized Domain Names. Because host
 * names in URLs are limited to ASCII characters only, Domain Names that contain
 * non-ASCII characters must be converted into ASCII using the Punycode scheme.
 * For instance, the Japanese character that translates into the English word,`'example'` is `'例'`. The Internationalized Domain Name, `'例.com'` (equivalent
 * to `'example.com'`) is represented by Punycode as the ASCII string`'xn--fsq.com'`.
 *
 * The `punycode` module provides a simple implementation of the Punycode standard.
 *
 * The `punycode` module is a third-party dependency used by Node.js and
 * made available to developers as a convenience. Fixes or other modifications to
 * the module must be directed to the [Punycode.js](https://github.com/bestiejs/punycode.js) project.
 * @deprecated Since v7.0.0 - Deprecated
 * @see [source](https://github.com/nodejs/node/blob/v16.9.0/lib/punycode.js)
