Description Joel R. Voss 2010-07-07 01:00:51 AEST 
When copying a file with newlines (and probably many other characters) to a server with scp, the newlines are converted to ^J. Since this is not a direct copy, I consider it a bug. I do not suspect that it is a feature though I have not checked yet which part of the code is causing this. In Linux and *nix, all characters are possible in filenames except null and slash. Unicode is one good reason for this.

Unfortunately this is an unfixable limitation of the scp (rcp) protocol (it uses a newline to indicate the end of the file metadata).  Use sftp if this bothers you.
