The enctype spells out multipart/form-data. So that's what you should use, and
then there's no particular encoding for you to do.

Try CURLFORM_FILE instead of CURLFORM_COPYCONTENTS to let libcurl read and
deal with the file on its own.

Do you have any other tool/client that speaks the correct protocol? Can you
compare what that sends with what your libcurl client sends?
