+.TH curl_mime_encoder 3 "22 August 2017" "libcurl 7.56.0" "libcurl Manual"
+.SH NAME
+curl_mime_encoder - set a mime part's encoder and content transfer encoding
+.SH SYNOPSIS
+.B #include <curl/curl.h>
+.sp
+.BI "CURLcode curl_mime_encoder(curl_mimepart * " part ,
+.BI "const char * " encoding ");"
+.ad
+.SH DESCRIPTION
+curl_mime_encoder() requests a mime part's content to be encoded before being
+transmitted.
+
+\fIpart\fP is the part's handle to assign an encoder.
+\fIencoding\fP is a pointer to a zero-terminated encoding scheme. It may be
+set to NULL to disable an encoder previously attached to the part. The encoding
+scheme storage may safely be reused after this function returns.
+
+Setting a part's encoder twice is valid: only the value set by the last call is
+retained.
+
+Upon multipart rendering, the part's content is encoded according to the
+pertaining scheme and a corresponding \fIContent-Transfer-Encoding"\fP header
+is added to the part.
+
+Supported encoding schemes are:
+.br
+"\fIbinary\fP": the data is left unchanged, the header is added.
+.br
+"\fI8bit\fP": header added, no data change.
+.br
+"\fI7bit\fP": the data is unchanged, but is each byte is checked
+to be a 7-bit value; if not, a read error occurs.
+.br
+"\fIbase64\fP": Data is converted to base64 encoding, then split in
+CRLF-terminated lines of at most 76 characters.
+.br
+"\fIquoted-printable\fP": data is encoded in quoted printable lines of
+at most 76 characters. Since the resulting size of the final data cannot be
+determined prior to reading the original data, it is left as unknown, causing
+chunked transfer in HTTP. For the same reason, this encoder may not be used
+with IMAP. This encoder targets text data that is mostly ASCII and should
+not be used with other types of data.
+
+If the original data is already encoded in such a scheme, a custom
+\fIContent-Transfer-Encoding\fP header should be added with
+\FIcurl_mime_headers\fP() instead of setting a part encoder.
+
+Encoding should not be applied to multiparts, thus the use of this
+function on a part with content set with \fIcurl_mime_subparts\fP() is
+strongly discouraged.
+.SH AVAILABILITY
+As long as at least one of HTTP, SMTP or IMAP is enabled. Added in 7.56.0.
+.SH RETURN VALUE
+CURLE_OK or a CURL error code upon failure.
+.SH EXAMPLE
+.nf
+ curl_mime *mime;
+ curl_mimepart *part;
+
+ /* create a mime handle */
+ mime = curl_mime_init(easy);
+
+ /* add a part */
+ part = curl_mime_addpart(mime);
+
+ /* send a file */
+ curl_mime_filedata(part, "image.png");
+
+ /* encode file data in base64 for transfer */
+ curl_mime_encoder(part, "base64");
