Name
mimepart:Encoder -- set mime part's encoder (V2.0)
Synopsis
mimepart:Encoder(enc$)
Function
This requests a mime part's content to be encoded before being transmitted.

Upon multipart rendering, the part's content is encoded according to the pertaining scheme and a corresponding "Content-Transfer-Encoding" header is added to the part.

Supported encoding schemes are:

binary
The data is left unchanged, the header is added.
8bit
Header added, no data change.
7bit
The data is unchanged, but is each byte is checked to be a 7-bit value; if not, a read error occurs.
base64
Data is converted to base64 encoding, then split in CRLF-terminated lines of at most 76 characters.
quoted-printable
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 Content-Transfer-Encoding header should be added with mimepart:Headers() 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 mimepart:Subparts() is strongly discouraged.
