| <pre class="api_stability_2">Stability: 2 - Unstable</pre><p><a href="http://mths.be/punycode">Punycode.js</a> is bundled with Node.js v0.6.2+. Use |
| <code>require('punycode')</code> to access it. (To use it with other Node.js versions, |
| use npm to install the <code>punycode</code> module first.) |
| |
| </p> |
| <h2>punycode.decode(string)<span><a class="mark" href="#punycode_punycode_decode_string" id="punycode_punycode_decode_string">#</a></span></h2> |
| <p>Converts a Punycode string of ASCII code points to a string of Unicode code |
| points. |
| |
| </p> |
| <pre><code>// decode domain name parts |
| punycode.decode('maana-pta'); // 'mañana' |
| punycode.decode('--dqo34k'); // '☃-⌘'</code></pre> |
| <h2>punycode.encode(string)<span><a class="mark" href="#punycode_punycode_encode_string" id="punycode_punycode_encode_string">#</a></span></h2> |
| <p>Converts a string of Unicode code points to a Punycode string of ASCII code |
| points. |
| |
| </p> |
| <pre><code>// encode domain name parts |
| punycode.encode('mañana'); // 'maana-pta' |
| punycode.encode('☃-⌘'); // '--dqo34k'</code></pre> |
| <h2>punycode.toUnicode(domain)<span><a class="mark" href="#punycode_punycode_tounicode_domain" id="punycode_punycode_tounicode_domain">#</a></span></h2> |
| <p>Converts a Punycode string representing a domain name to Unicode. Only the |
| Punycoded parts of the domain name will be converted, i.e. it doesn't matter if |
| you call it on a string that has already been converted to Unicode. |
| |
| </p> |
| <pre><code>// decode domain names |
| punycode.toUnicode('xn--maana-pta.com'); // 'mañana.com' |
| punycode.toUnicode('xn----dqo34k.com'); // '☃-⌘.com'</code></pre> |
| <h2>punycode.toASCII(domain)<span><a class="mark" href="#punycode_punycode_toascii_domain" id="punycode_punycode_toascii_domain">#</a></span></h2> |
| <p>Converts a Unicode string representing a domain name to Punycode. Only the |
| non-ASCII parts of the domain name will be converted, i.e. it doesn't matter if |
| you call it with a domain that's already in ASCII. |
| |
| </p> |
| <pre><code>// encode domain names |
| punycode.toASCII('mañana.com'); // 'xn--maana-pta.com' |
| punycode.toASCII('☃-⌘.com'); // 'xn----dqo34k.com'</code></pre> |

| <h3>punycode.ucs2.decode(string)<span><a class="mark" href="#punycode_punycode_ucs2_decode_string" id="punycode_punycode_ucs2_decode_string">#</a></span></h3> |
| <p>Creates an array containing the decimal code points of each Unicode character |
| in the string. While <a href="http://mathiasbynens.be/notes/javascript-encoding">JavaScript uses UCS-2 |
| internally</a>, this function |
| will convert a pair of surrogate halves (each of which UCS-2 exposes as |
| separate characters) into a single code point, matching UTF-16. |
| |
| </p> |
| <pre><code>punycode.ucs2.decode('abc'); // [97, 98, 99] |
| // surrogate pair for U+1D306 tetragram for centre: |
| punycode.ucs2.decode('\uD834\uDF06'); // [0x1D306]</code></pre> |
| <h3>punycode.ucs2.encode(codePoints)<span><a class="mark" href="#punycode_punycode_ucs2_encode_codepoints" id="punycode_punycode_ucs2_encode_codepoints">#</a></span></h3> |
| <p>Creates a string based on an array of decimal code points. |
| |
| </p> |
| <pre><code>punycode.ucs2.encode([97, 98, 99]); // 'abc' |
| punycode.ucs2.encode([0x1D306]); // '\uD834\uDF06'</code></pre> |
| <h2>punycode.version<span><a class="mark" href="#punycode_punycode_version" id="punycode_punycode_version">#</a></span></h2> |
| <p>A string representing the current Punycode.js version number. |
