Description Marc Schiffbauer 2012-04-18 11:34:41 UTC
Hi,

this bug has been there in the past and something about it has been fixed. I do not know any bug number, sorry.

While this is working most ogf the time time, I just got an email where it still does NOT work.

Displaying that email works quite fine for that particular email, but when I hit the reply button, all text that is transferred to the composer as quote is decoded twice or sowmthing like that producing strings like "ä" for a german a-umlaut (ä) for example.

I had a quick look at the mail headers like "Content-Type:" and the Content-Type of the mime parts.

It seems like kmail (-composer?) fails at understanding/decoding special crafted (nested?) mime attachements . I have compared a working mail and a non working mail, which both are quite similar and noticed the following differences:

WORKING mail:
============
Header:
Content-Type: multipart/mixed; boundary="------------090808080701020801080608"

Body:
This is a multi-part message in MIME format.
--------------090808080701020801080608
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

some umlaut: =C3=BC
--------------090808080701020801080608

FAILING mail:
===========
Header:
Content-Type: multipart/mixed; boundary="===============4151591153882929492=="

Body:
--===============4151591153882929492==
Content-Type: multipart/alternative;
 boundary="========GMXBoundary37091334746530755927"

--========GMXBoundary37091334746530755927
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: quoted-printable

some umlaut: =C3=BC
--========GMXBoundary37091334746530755927
Content-Type: text/html; charset="utf-8"
Content-Transfer-Encoding: quoted-printable

<span>some umlaut: =C3=BC</span>

--========GMXBoundary37091334746530755927--

--===============4151591153882929492==
Content-Type: text/plain; charset="us-ascii"
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit
Content-Disposition: inline

some footer

--===============4151591153882929492==--



Reproducible: Always

Actual Results:  
Non-ascii chars in editor are presented like "=C3=BC" instead of "ä" for example for some mails

Expected Results:  
Non-ascii chars in editor are presented like "ä" properly

mutt does it all right
Comment 1 Laurent Montel 2012-04-25 06:53:27 UTC
perhaps you can add directly an email which has a problem here.
Thanks

Example email

Hello Laurent,

please see attached mbox File. I had to anonymize the text.

Open with Ctrl-O -> Looks correct
Hit "r" to reply: garbled non-ascii chars

Thanks for your hard work on kmail!

Comment 3 Laurent Montel 2012-04-25 10:09:32 UTC
Are you sure that you don't have problem with your charset ?
Here is fine.

Look at configure->editor->charset
I have:
us-ascii
iso-8859-1
utf8(local)
utf8

Please screenshot after your "r" on your ano.mbox please.

Hi Laurent,

I have the exactly same charset settings.

here is a screenshot.
What else can I provide?

Don't know for the moment why for you reply is not good.
Will continue to investigate.
Comment 6 Marc Schiffbauer 2012-04-25 13:57:41 UTC
Thanks! I hope you can find something that may cause this.
I don't know whether this is relevant, my locale:

LANG=de_DE.UTF-8
LC_CTYPE="de_DE.UTF-8"
LC_NUMERIC="de_DE.UTF-8"
LC_TIME="de_DE.UTF-8"
LC_COLLATE="de_DE.UTF-8"

Comment 7 Christophe Marin 2012-04-25 22:09:37 UTC
in KMail settings, composer, charset.. is "Keep original charset ..." checked ?

Try to uncheck it.

I unchecked it. Now it looks correct!  Thanks!

But: Should we nevertheless consider that a bug? Because when viewing the original mail all looks correct. Only the composer does something to the text that is not entirely correct when this setting is enabled.

Or: Why should someone enable that setting? Should it perhaps be removed?
Comment 9 Christian 2012-08-04 13:57:50 UTC
Same problem here. The email below (anonymised a bit) doesn't work - it is displayed correctly, but when replying, the characters in the quoted message are messed up.
The box "when replying, keep original message charset if possible" was checked in the settings. When I uncheck it, the bug is not present and everything works fine.

Comment 10 Marta Rybczyńska 2013-09-30 19:49:58 UTC
Same problem. Suspected the encoding list that has us-ascii at the top, but moving UTF-8 there did not help. Only removing the 'Keep the encoding' option helps.

I had the same bug and unchecking helped.
Comment 14 Till Schäfer 2016-11-04 15:47:06 UTC
i can confirm this bug for kmail 5.3.2
Comment 15 SH 2017-06-25 16:45:38 UTC
It happens to me too, very often. Hebrew text, when quoted in a reply, is garbled and unreadable. I'm not sure about English or other languages.
Comment 16 Hans-Peter Jansen 2019-10-18 18:17:04 UTC
Still confirmed for 5.12.2 (as of openSUSE Tumbleweed 20191014).

Unchecking "Keep original charset..." fixed it, but since this option is enabled by default, it would probably be a good idea to change the default until this issue is finally fixed.
Comment 17 null 2020-05-05 22:45:56 UTC
(In reply to Hans-Peter Jansen from comment #16)
> "Keep original charset..." [...] is enabled by default
Are you sure about that? I tested KMail 18.08 and current git master, and in both cases "Keep original charset..." was unchecked by default.

Anyway, I simplified the mail attached in Comment 2 a bit (see below).

Findings (with "Keep original charset..." checked):
- "Content-Type: multipart/mixed;" is necessary to reproduce
- after removing the "€" symbol (first line), "können" is not garbled anymore

Reduced test case:

Git commit 29a5a05e2078b75f0a994e29e92707e3ec81e2d1 by Laurent Montel, on behalf of Fabian Vogt.
Committed on 09/03/2023 at 07:27.
Pushed by fvogt into branch 'master'.

Fix fallback path in MessageFactoryNG::applyCharset

In the case that the codec of the original message could not encode the reply,
it was still set as charset but the body encoded with the fallback codec.
This resulted in replies having messed up encoding.
It can be triggered by replying to multipart mails which define the charset
in parts only or if the reply template ends up with other special characters.
