Hi, I have a messages that has an ISO-8859-1 encoded Subject ("=?ISO-8859-1?Q?Sch=F6n") but a multipart utf8 encoded body ("Content-Type: text/plain; charset=utf-8" and "Content-Type: text/html; charset=utf-8") The subject is displayed correctly but body only if the text part is displayed. Obviously, for the html part the header encoding is also assumed for the body. Not even changing view -> character encoding from Automatic to utf8 helps. Saving the mail and inspecting it confirms that the encoding of both parts is actually utf8.
Maybe I should add that both parts have Content-Transfer-Encoding: 8bit
