title: Internationalization of task comments using Camunda rest-engine
body: <p>I setup Camunda as a web-service in tomcat and connect to it via my .NET web application.
  When I create comment on task with following rest API</p>
  <p>POST /task/{id}/comment/create</p>
  <p>with message in Unicode (Persian), for example “این نمونه است”
  and I got the correct message in response request. Also the comment is saved in persian correctly in the camunda database.
  But when I get the comment using this API</p>
  <p>GET /task/{id}/comment/{commentId}</p>
  <p>I got message as “?? ???”
  I tried it with postman and got same result.
  I also set the JAVA_TOOL_OPTIONS=&quot;-Dfile.encoding=UTF-8&quot; in tomcat but it does not solve it.
  I am wonder what is the root of problem?</p>
  <p>Thanks in advance</p>
