I notice how all of them are Windows servers...

What libcurl and libssh2 versions are you using?

I've never seen anything like it. But they're _after_ the closing quote of the
scp command so are you sure that's even related to what is sent by
curl/libssh2 ?

Sorry, I can't as I don't run Windows.

I would suggest that you switch over to using plain libssh2 first to track
down the SCP problem. If you build and run a simple scp transfer example
directly using libssh2, will that work or not? If not, the problem is in that
library and we should persue the debugging there (on the libssh2 mailing
list).

Please make sure that you use recent versions of both libcurl and libssh2 to
take advantage of the latest bug fixes and improvements.
