We face exceptions as the one given below often, but cannot reproduce it. The next run usually performs w/o any glitch.

  Are there non-ASCII characters in the changelog when this occurs? It is possible there is a file encoding issue, though

  No (well, at least not visible ones)
  
  In the last two days the number of failures is increasing for unknown reasons. The last update to the jenkins installation was already some weeks ago.
  I've discovered https://issues.jenkins.io/browse/JENKINS-43176 - maybe it's related.
  
  Since there are many difference pipelines running on the system a workaround to modify pipelines would be a lot of work todo.
