title: How to convert Emoji from Unicode in PHP?
body: <p>I use this <a href="http://apps.timwhitlock.info/emoji/tables/unicode" rel="noreferrer">table of Emoji</a> and try this code:</p>
  
  <pre><code>&lt;?php print json_decode('"\u2600"'); // This convert to ☀ (black sun with rays) ?&gt;
  </code></pre>
  
  <p>If I try to convert this <a href="http://apps.timwhitlock.info/unicode/inspect/hex/1F600" rel="noreferrer">\u1F600</a> (grinning face) through <code>json_decode</code>, I see this symbol — <code>ὠ0</code>.</p>
  
  <p>Whats wrong? How to get right Emoji?</p>
