title: How can I use HTML symbols like arrows in javascript?
body: <p>I have a script that generates a list of <code>&lt;form&gt;</code> tags with multiple inputs and buttons inside. I want to use an arrow (&#8593;) on a button but when I write</p>
  
  <pre><code>buttonUp.value="&amp;#x2191;";
  </code></pre>
  
  <p>it doesn't work.<br>
  Instead of showing &#x2191;, the button shows the raw code on the page.
  How can I make the arrow display on the button?</p>
