title: Convert CharCode to Char?
body: <h1>What I need</h1>
  <p>ok I googled this and there are many tutorials on how to get the charCode from the character but I cant seem to find out how to get the character from the charcode.</p>
  <p>Basically I am I am listening for the <code>KeyDown</code> event on a <code>TextInput</code>.</p>
  <p>I prevent the char from being typed via <code>event.preventDefault();</code></p>
  <p>Later I need to add the text-char to the TextInput.</p>
  <p>I can get the charCode via <code>event.charCode</code> so if I can turn that into a string I can save it for later user.</p>
  <h1>Why I need it</h1>
  <p>Basically I am making a TextInput, that that I can set to display default text in it. When A user types into it, I want to remove the default text first then add the user typed text.</p>
  <p>Currently I am either removing it all, or ending up with both.</p>
