My advice is don't try.  I mistrust the kinds of translation headaches that
come from passing around "control" characters of that sort in EBCDIC,
ASCII, or whatever else there is in the world.

You didn't say, but I assume your source string is in some EBCDIC code page
and that the \r\n is not present already in the input?

I would instead figure out how to pass the length of each line in some
fashion and make that part of what you pass in (I assume this multi-line
string is passed in as one large parameter?).  You can pass it as some
suitable second parameter.  You could define a convention like "a three
digit number tells how many lines and then N three digit numbers tell how
long each string is" for the second parameter.  That's probably easiest and
no translation worries.

Java can then trivially add the \r\n itself if that's required in however
you define the mail handling code in Java.
