Encode raw data into something suitable for transport to other systems.
The encoding can be any of
| "7bit" |
| "8bit" |
| "base64" |
| "binary" |
| "quoted-printable" |
| "x-uue" |
| "x-uuencode" |
|
The encoding string is not case sensitive. For the x-uue encoding,
an optional filename string may be supplied.
If a nonzero value is passed as no_linebreaks , the result string
will not contain any linebreaks (base64 and quoted-printable
only).
