Each bit is a +Boolean flag used while encoding a MIME tree or multipart form data. + +Available bits are: +.IP CURLMIMEOPT_FORMESCAPE +Tells libcurl to escape multipart form field and file names using the +backslash-escaping algorithm rather than percent-encoding (HTTP only). + +Backslash-escaping consists in preceding backslashes and double quotes with +a backslash. Percent encoding maps all occurrences of double quote, +carriage return and line feed to %22, %0D and %0A respectively. + +Before version 7.81.0, percent-encoding was never applied. + +HTTP browsers used to do backslash-escaping in the past but have over time +transitioned to use percent-encoding. This option allows to address +server-side applications that have not yet have been converted. + +As an example, consider field or file name \fIstrange\\name"kind\fP. +When the containing multipart form is sent, this is normally transmitted as +\fIstrange\\name%22kind\fP.
