title: Typescript fields with special characters
body: <p>We need to call a REST API from out node.js code in Typescript and would like to have corresponding types for requests and responses. 
  Unfortunately, JSON for the interface we are given contains fields such as:</p>
  
  <pre><code>{...
      "@ID": "1234567890",
          ...
      "@Name": "something",
      "#text": "content",
  ...
  }
  </code></pre>
  
  <p>We have been told, that this stems from a limitation of the other end's automated "JSONifier" and cannot be changed. How do we set up interfaces that fit for this?
  The following obviously won't work:</p>
  
  <pre><code>  export interface Request {
      @ID: string;
      @Name: string;
      #text: string;
      ...
    }
  </code></pre>
