title: Angular 6 Kendo Grid Field names with special characters
body: <p>I am creating a dynamic grid in Kendo UI for Angular, the columns are created from
  database columns, that are unfortunately in Swedish, that has the special characters å, ä and ö</p>
  
  <p>for example, "ändradAv" (en: changedBy)</p>
  
  <p>I am getting the error:</p>
  
  <blockquote>
    <p>Grid column field name 'ändradAv' does not look like a valid JavaScript identifier.
                    Identifiers can contain only alphanumeric characters (including "$" or "_"), and may not start with a digit.
                    Please use only valid identifier names to ensure error-free operation.</p>
  </blockquote>
  
  <p>Everything is working properly and I am getting my columns as well as the data but I would like to get rid of this message.</p>
  
  <p>Any suggestions?</p>
