mailman admin page shows in KOI-8 charser .... thouse message body with this headers Content-Type: text/plain; charset=windows-1251 Content-Transfer-Encoding: 8bit
shows ugly, with wrong charset. When I change page charset from koi-8 to windows cp1251, mailman admin page is ugly, but message is OK .....
It would be possible to patch Mailman/Cgi/admindb.py with the attached patch to decode this "message excerpt" before displaying it, but then you would have the issue that
This is exactly what I would expect to happen in all cases. I suggested this would occur when I wrote on 2007-02-13 10:53: the
characters in the box in your screenshot would be Windows CP1251 characters which would probably still be garbled when displayed in the character set of the rest of the page.
The only question is why doesn't this occur when the message is Content-Type: text/plain; charset=windows-1251 Content-Transfer-Encoding: quoted-printable since all the patch does is convert the quoted-printable encoding back to the original 8bit. At some point in the future, we expect that mailman will represent everything internally in Unicode. At that time, this issue may be fixed. Until then I don't anticipate this behavior to change. The only advice I can offer is that in cases where it is important to see the message body correctly in order to decide what action to take on a particular held message, you either switch character sets in your browser when you need to see the message body, or you refer to the original message attached to the 'held message notice' email sent to the moderators which should display properly in your email client. ---------------------------------------------------------------------- Comment By: dudeua (dudeua) Date: 2007-04-03 02:07 Message: Logged In: YES user_id=1718234 Originator: YES mailman admin page shows in KOI-8 charser .... thouse message body with this headers Content-Type: text/plain; charset=windows-1251 Content-Transfer-Encoding: 8bit shows ugly, with wrong charset.

In the case of quoted-printable encoding, all non-us-ascii-printable bytes are encoded as '=xx' where xx is the hex value of the corresponding byte. The 'decode=True' argument added by the patch causes these '=xx' codes to be converted back to the original bytes for display in the admindb interface. In the case of 8bit encoding, all bytes are represented as themselves and the 'decode=True' argument does nothing. The result should be the same. ---------------------------------------------------------------------- Comment By: dudeua (dudeua) Date: 2007-04-02 06:30 Message: Logged In: YES user_id=1718234 Originator: YES Hi msapiro, Thanks for your patch! all work fine. but today i meet ne problem.

Thanks! ---------------------------------------------------------------------- Comment By: Mark Sapiro (msapiro) Date: 2007-02-13 10:53 Message: Logged In: YES user_id=1123998 Originator: NO The screenshot is unnecessary. I understood exactly what the issue was from your original description. I know you only see the problem in the "message excerpt" in the admindb message detail. I tried to explain that the reason for this is that this excerpt is not decoded. It would be possible to patch Mailman/Cgi/admindb.py with the attached patch to decode this "message excerpt" before displaying it, but then you would have the issue that the characters in the box in your screenshot would be Windows CP1251 characters which would probably still be garbled when displayed in the character set of the rest of the page. Also, my suggestion to set admin_immed_notify to 1 was not intended to 'correct' this display. It causes this message to be also sent to you in an email so that if it is necessary for you to see the message text in order to decide what action to take with the message, you can see the text in the email notice.

It already setted to 1; Pleasee see attacged screenshot. I can't use MUA (mail agent), because I meet problem with encoding only at admin area. Thanks for help.

It is an encoding. That is, it is a way of representing data which contains non-printable, us-ascii characters using only the us-ascii character set as required by RFC2822 for email messages. The issue here is that encoded message bodies are not decoded for display in the admindb message detail. This may change in the future, but then there _will_ be character set and content-type issues. These are more complicated as in general, different message parts may have different character sets and may not even be text. Currently, if you really need to see the decoded text, you need to set admin_immed_notify to Yes so you get an email notice of the held message and use an MUA (mail client) that shows you the decoded message in the notice. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100103&aid=1658920&group_id=103
