title: Unicode character in propertyname
body: <p>I need a response from a public API that contains the letter ø (\u00f8).
  I'm using angular, and I use an interface to make my responses typed.</p>
  <pre><code>export interface Response{
    øl: string; // instead of ø I would like to use \u00f8 (or something similiar)  
  }
  </code></pre>
  <p>The problem is I have some international coworkers that do not have ø in their alphabet. Creating strings with Unicode is easy, but how can I do it with property names?</p>
