UTF-8 problem with rmail From line

UTF-8 problem with rmail From line

[İsmail Dönmez]

Hi,

This is a very old problem for me at least 2-3 years. But since rmail
got active development again. Here goes the bug report. My name in
/etc/passwd is defined as:

cartman:x:1000:1000:İsmail Dönmez,,,:/home/cartman:/bin/zsh

Now in emacs when I do C-x m , I see the following:

From: "=?utf-8?Q?=C4=B0smail_D=C3=B6nmez?=" <cartman@uzaklarda>
To:
Subject:
--text follows this line--


So the name is pretty much garbage now. Is this somehow expected or is it a bug?

Regards,
ismail

That's not garbage, that's how non-ASCII characters in email addresses
need to be encoded.

The problem is that mail transport does not allow (or at least didn't
allow in the past) non-ASCII characters in any of the mail headers,
because various mail servers need to look at the headers.  So Emacs
encodes the non-ASCII characters in quoted-printable encoding.

How about a tooltip or local help over the header content, to display
the decoded value?

Post 23.1, this would be a good idea.

How about making sendmail-send-it do the encoding,
so that users can see the names in a readable form
in the *mail* buffer?

It would also be convenient for Rmail to automatically decode
all the header fields that it displays.

This would be the best option imho.

Not all mail backends in Emacs use sendmail-send-it, IIRC.

No, but they should all handle non-ASCII chars in the headers.

Well, yes, but the encoding needs to happen when you send the message,
not before.
