Account for different parsing technique in EnsLib.HL7.Service.FileService??

I have a system that is sending Line Breaks\Carriage Returns within the text of a field that is breaking the parsing of the message. Does anyone have a way to get around this?

here is what I receive... 

ZPR|29|937952|UH|Physician Assistant - Certified|Primary Privileges:  Physician Assistant|Care of simple fractures including extremity, rib and clavicle; including skeletal
immobilization||

as EnsLib.HL7.Service.FileService parses the message it puts immobilization on a new line because of the hidden line break, and the rest of the message is lost.

I tried using tr, sed, perl from a unix command line to reformat the message before it gets to Ensemble but I can't get the right combination to make sure the Line Feed is not in that field. The users of the system don't understand what I am asking of them and the vendor of the system has been no help either.

Does anyone have a way to create a custom parser that only looks for SEGMENTS to parse the message apart?
