From the reply to a post of mine in a clpmisc thread (link @ GG), both to the author's (Peter J. Holzer) and my own surprise:

To my surprise they are portable at least between Unix and Windows. Pe
+rl
seems to automatically detect the line endings and convert them to
\x{0A} at compile time. A string written as a here document always
contains simple "\n" characters as line endings regardless of whether
the source file contained CRLFs or LF and whether it's executed on
Windows or Unix.
