Or even
While Quoted-Printable encoding MUST be used when necessary to encode
non-US-ASCII characters, it SHOULD NOT be used unless required for such
uses; that is, if the SMTP server supports 8BITMIME, or the message
only contains US-ASCII characters, there is no need for
Quoted-Printable encoding.
The intent of Format=Flowed is to allow user agents to generate flowed
text which is non-obnoxious when viewed as pure Text/Plain; use of
Quoted-Printable hinders this and may cause Format=Flowed to be
rejected by end users.
