libcurl does no particular encoding of the file name but blindly assumes that
it can be put there as 8bit binary. RFC1867 section 3.3 suggests:

    The original local file name may be supplied as well, either as a
    'filename' parameter either of the 'content-disposition: form-data'
    header or in the case of multiple files in a 'content-disposition:
    file' header of the subpart. The client application should make best
    effort to supply the file name; if the file name of the client's
    operating system is not in US-ASCII, the file name might be
    approximated or encoded using the method of RFC 1522.

... but no such encoding is being done currently.
