title: How to return letters from UTF-16
body: <p>I need to return the letters in a word in alphabetical order. I got the following problem, I don't know how to return the letters from numbers, I tried to use <code>String.fromCharCode()</code> and <code>charAt()</code> but it did nothing.
  I got:</p>
  
  <pre><code>function AlphabetSoup(str) { 
  
    let spl = str.split('');
  let res = spl.map(order =&gt; order.charCodeAt()).sort((a,b) =&gt; b - a).reverse();
  
   return res;
  }
  </code></pre>
  
  <p>So the result is <code>[ 98, 99, 100, 101, 101, 111, 114, 116, 121 ]</code> </p>
