Re: Incorrect rendering of accented characters in HTML e-mail (Gnus)

Sorry for the previous post. Long lines with multipart messed up the
nntp post. Here it goes again.

I confirm that this does not happen with all e-mails. Only for messages
with a "multipart" enclosure but not all of them. A quick check tells me
that the problem appears with

,----
| < #multipart type=mixed>
| < #part type=text/plain format="flowed" charset="utf-8"
| disposition=inline nofile=yes> 
`----

and

,----
| < #multipart type=alternative>
| < #part type=text/plain format="flowed" charset="utf-8"
| disposition=inline nofile=yes> 
`----

But not for this one

,----
| < #multipart type=alternative>
| < #part type=text/plain charset="iso-8859-1" disposition=inline
| nofile=yes>
`----

So I guess that the problem is the utf-8 encoding.

I am on emacs git master branch and I have been having the problem for
several months now, so this is coherent with your guess.

What I understand is that:
1. html is not the issue, but the multipart, since the text/plain part
   also gets incorrectly encoded
2. only happens when charset is utf-8 and not iso-8859-1
3. only happens with nnmaildir, since I have used nnimap to download the
   same messages from the same server and they are correctly displayed
   by Gnus
4. since the «dummy edit» works, this means that the issue is corrected
   when emacs opens the message in edit mode

Thanks for any feedback.
