Stripping Illegal Characters from message Stream in Mule

Question

I have experienced an issue where there was an illegal character in a source system which when it hit the DataWeave transformer threw an error. We have since fixed the data in the source system, however we should be able to strip this illegal character in Mule. Here is the error that occurred when it hit the DataWeave Transformer. I need help in how to and where to strip these "Illegal" characters.

The flow is expecting a valid SOAP message. If the message is invalid then what you did is the correct solution: fix the source system. Just removing characters doesn't mean the message will make sense.
