The characters can't be encoded because we don't know what the character set it. The only patch that would be acceptable to us would have a configurable character set ("assume_8bit: iso-8859-1") and would sanity check and encode the untagged 8-bit according to that.Maybe the best solution would be a filter to change the message body encoding using quoted-printable instead of putting X everywhere, and change headers to also use the appropriate encoding. What do you think about this ?
