Encoding 7-bit World 8-bit World 8->7 translation
8BIT impossible OK QUOTED-PRINTABLE or BASE64
7BIT OK OK none needed
BINARY impossible OK BASE64
BASE64 OK OK none needed
QUOTED-P... OK OK none needed
It is a big difference between 8BIT and BINARY. You can theoretical
send BINARY files in the 8-bit world but only theoretical a lot
of transportation protocols assumes a limited line length.
This is also the reason to have both 8BIT and BINARY. So we have
to use BASE64 or some other translation scheme to send binary
