  <p>I get this error when running the agent:</p>
  
  <blockquote>
    <p>Unable to Parse JSON string:
    Missing a comma or '}' after an object member. offset 1791</p>
  </blockquote>
  
  <p>After some testing, I found out that the error is coming from a special character in the json (ø in '... falling to 3øC next ...').</p>
  
  <p>Can anybody help me out on how to avoid/convert characters that could cause issues when parsing the JSON?</p>
  
  <p>PS: The openntf JSON parser handles the json correctly.</p>
