Winsock protocol failed to translate buffer to socket0 when buffer contains backslash

Hi,

I'm trying to send the below TCP buffer to our TIBCO interface (the buffer was provided by dev team). I have parameterized this data in the script. But I'm getting error 9013 Unable to transfer buffer. When I verified each special symbol in the buffer I found it is the backslash "\" between FNAME and LNAME which cannot be translated by LR. I have tried putting escape characters i.e. \\ but same error.

please can anyone guide what could be wrong here?
