Multipart/mixed request using postman

Hi

I want to implement an API which accepts multipart/mixed. Delimiter for header values in body of multipart/mixed is documented to be \r\n as per [RFC1341(MIME) : 7 The Multipart content type]

I have been able to work with the above delimiter using curl. But, I could not find a way to pass on \r\n via postman. Postman always sends removes \r when pasted from a text editor.

Could you please provide a solution.

Thanks
