All,
I have a message flow that receives XML from a Windows based application and we have WMB running on AIX. We have some error messages in the queues with the "Invalid character (Unicode: 0x1A)" error.

I have gone through previous posts on this subject in this forum and it looks like the consuming application is either sending 0x1A or 0x1A being a substitute character, they are sending a character that is not valid.

Before I contact the consuming application, I thought I would look at the error message in the queue to see what they are sending us. When an exception happens we store both the InputExceptionList Tree and the InputRoot.XML Tree in the ERR queue.

I am not able to see 0x1A in the original message in the error queue and furthermore when I extract the original message from the error queue and send it through the input queue again, it works fine.

I am not able to understand how this is possible. The original message in the error queue should have the Invalid character and it should fail again when I try to reprocess it. Is it not?

Thanks!
