I've narroved this down to this setting of default_charset in imp/lib/base.php: Thanks - this was the key piece of information. We did charset conversion in MIME_Headers::getOb() after we did MIME decoding, when the order should be reversed. I wasn't seeing this in IMP HEAD since we no longer use the MIME_Headers:: version of getOb(). This has been fixed in HEAD and Horde 3.1.2.

I've narroved this down to this setting of default_charset in imp/lib/base.php: // Set default message character set, if necessary if (isset($prefs) && ($def_charset = $prefs->getValue('default_msg_charset'))) { $GLOBALS['mime_structure']['default_charset'] = $def_charset; $GLOBALS['mime_headers']['default_charset'] = $def_charset; } If I remove this block, then 8-bit characters are shown correctly in Subject header in the reply message window.

Still don't see any problem with CVS FRAMEWORK_3 versions of IMP/Horde. Tested with a subject including the character "ö" that was sent in both UTF-8 and ISO-8859-1. Is there an preference setting that could interfere with this charset and multibyte regocnition in Imp or Horde? Could this be somehow related to the charset information that browser is sending to Horde? For me this situation is repeatable in IE and Firefox browsers with Imp running on Linux or Solaris OS. It does not matter if user is using english or finnish locale in Horde.

Possibly a related issue to ~~Bug #3746~~? As far as I can understand it is not the same issue. It seems that charset are converted between iso-8859-1 and utf-8 either too many times or too few times. Somehow somewhere the multibyte charset recognition is not working and text with utf-8 charset is shown as if it were iso-8859-1. This issue appeared after Imp release 4.1.0.

I can't reproduce this. In the message you are replying to, is the subject MIME encoded or are there bare 8-bit characters in the Subject (which would mean it is a very broken message)? Subject text in the original message is correctly MIME encoded. But when you open this message to compose windows eg. to reply then the subject text looks like it is converted from iso-8859-1 to utf-8 but then shown as if it still were in iso-8859-1charset.

1. Compose message that has 8-bit characters in it's subject 2. reply to this message, and 8-bit characters in the Subject: seems to be in utf-8, but they are shown as though they were in iso-8859-1 eg. letter 'ö' (one character) is shown as 'Ã¶' (two characters).
