Searching for carriage return in an HL7 field

A vendor is sending an HL7 message where they are hitting the enter key within the field. I am looking for a way to concatenate the lines.  I want to know if there id a way to search the field for a carriage return and piece together the field.  This is an example of what they are sending:

NTE|1||Fake Interpretation A Overall Summary. Patient presents with abnormal SR and RHR. 
Fake Interpretation B 80/120
Fake Interpretation C  - HR 55 BPM|
