105+
When encountering a non-ASCII message or subject that does not
106+
declare its encoding, add headers/quoting to indicate it is
107+
encoded in <encoding>. Default is the value of the
108+
'sendemail.assume8bitEncoding'; if that is unspecified, this
109+
will be prompted for if any non-ASCII files are encountered.
110+

111+
Note that no attempts whatsoever are made to validate the encoding.
