XMLRPC is XML, and XML normalizes line feeds:

    http://www.w3.org/TR/2004/REC-xml-20040204/#sec-line-ends

relying on non-standard line terminators in text is fragile and horridly out-
dated; if the data you're sending qualifies as text, send it as text, and do
the conversion at the end points (if at all necessary).

if it's not text, use the binary wrapper.

how are you rendering things if you have problems treating a line feed
as a line feed?  that's rather unusual; most Windows applications have
no problems handling line feeds properly, so I'm not sure why it has to
be a problem in your application...
