Use Notepad++ to replace "\r" to "\\n\\\r" of desired contents by "Extended" model in Find Replace dialog.
Eg.

Assign

A(CR)(LF)
B(CR)(LF)
C(CR)(LF)
D

to variable XYZ.

First, replace "\r" to "\\n\\\r"

A\n\(CR)(LF)
B\n\(CR)(LF)
C\n\(CR)(LF)
D

In addition, put above result into XYZ; for instance,

var XYZ = "A\n\(CR)(LF)
B\n\(CR)(LF)
C\n\(CR)(LF)
D";
