We run an app that has a published webservice thats called by a service bus. We received a message that contained the following code in a string:  this translates to: UTF-8 (hex)0x08 (08) (A control character http://www.fileformat.info/info/unicode/char/0008/index.htm) This returns the following error: Exception occurred while processing webservice request -------- com.mendix.integration.WebserviceException: Internal server error at

scala.concurrent.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107) The problem is that 0x08 is not accepted by XML 1.0 but the original string should be accepted and in the Modeller I have not yet found a section where I can control encoding and decoding of these entries. Is there any way to mitigate this issue since we will see more of these strings popping up in our webservice?
