Thanks both six1 and Alex but thats not really the point, while its easy to work around, I don't think it should be like that.
"\n" is, obviously, a C newline, migrated to Javascript and then to JSON, by time it get to there, its not a Linefeed, its a newline, should be translated to a pascal LineEnding, and thats either #10 on Unix, #13#10 on Windows. (was #13 on Mac long, long ago).
Or so I think .....
