set generally shouldn't be encoded. The = character itself must be encoded, though; it's encoded as =3D. Also,
space and tab characters at the ends of lines must be encoded (as =20 and =09, respectively); this keeps broken
gateways from eating them. If a line ends with = followed by CR-LF, those characters are ignored; this lets you
continue ("wrap") a long line. Lines must be no more than 76 characters long, not counting the final CR-LF. Longer
lines will be broken when the message is encoded and joined again by decoding.
Quoted-printable text was designed to be (mostly) readable by people with non-MIME mail programs.
