Re: [BKARTS] =20s and such



For some reason the messages from this list are being converted to the
MIME Quoted-printable encoding. Your mail-reading program, however, does
not realize that the mail has been encoded this way. Either the
information saying *how* it was encoded has been lost, or your mail
reader does not understand this encoding type.

The messages I receive from the list include (amongst many others) the
following headers:
Content-Type: text/plain; charset="iso-8859-1"; format=flowed
Content-Transfer-Encoding: quoted-printable
X-MIME-Autoconverted: from 8bit to quoted-printable by mx3.syr.edu id
jAPEITXq011862

Either you are losing this header information, or your mail reader
doesn't understand the Content-Transfer-Encoding header, or it doesn't
understand the particular encoding quoted-printable.

The quoted-printable encoding essentially replaces everything except the
basic printable characters from the original ASCII character set with
=xx where xx is the hexadecimal value of the character. There are a
couple of special cases: line breaks are left as is, the equals sign '='
must be encoded as =3D, and blank and tab are left as is unless they are
the last character in the line in which case they are encoded as =20 and
=09 respectively. The line length of the encoded text is also limited,
so if it is necessary to break a line, a = is inserted at the end of the
line to indicate that this is an additional line break.

This is a reasonably effective encoding to use to map text that is
mostly ASCII into text that is *all* ASCII and has limited line length.

See http://en.wikipedia.org/wiki/Quoted-printable for perhaps a little
more information.
