Fri, 10 Apr 2026 17:02:28 +0000 https://bugs.horde.org/ticket/9020 Subject charset problem Subjects for messages containing foreign characters are either not display at all or show an '?' instead of the character. This is only true in the Folder display window - where I see all my messages along with their subjects. When I open the actual message, the subject shows fine with the proper characters. Examples of words include: Tecnológica , displays as: Tecnol?gica dólar , displays nothing at all. empty subject line I checked the html source and there really is nothing where the subject is supposed to be. However, when I open the message the subject is properly there. Thank you!

Wed, 12 May 2010 16:54:01 +0000 https://bugs.horde.org/ticket/9020#t58794 We are running the following: php-5.3.2 with this extension: IMAP c-Client Version 2006j Is this a known bug in the IMAP c-Client extension ? Thu, 13 May 2010 04:26:14 +0000 https://bugs.horde.org/ticket/9020#t58797 I just updated to version 2007e of the c-client library and the same problem occurs.

Hi Jan, I just fixed the issue by adding the following in mailbox.php at line 737: $msg['subject']=utf8_encode($msg['subject']); right after $msg['subject'] = $imp_ui->getSubject($ob->subject); the code now looks like: if (!empty($ob->subject)) { $msg['subject'] = $imp_ui->getSubject($ob->subject); $msg['subject']=utf8_encode($msg['subject']); } this effectively solves the problem and displays the characters properly. Can you confirm if this is just a bug on our systems ( and therefore we should make a note of it and update IMP ourselves ) or if it's a general issue with IMP that will be fixed in future releases ? We also had a very hard time with subjects encoded with ISO-8859. I submitted more info to the mailing list but basically the solution was to have NLS::getCharset return ISO-8859-1 instead of UTF-8 Sat, 15 May 2010 15:56:16 +0000 https://bugs.horde.org/ticket/9020#t58836 >> It could also be the imap server's fault.

I > submitted more info to the mailing list but basically the solution > was to have NLS::getCharset return ISO-8859-1 instead of UTF-8 > I just realized that encoding the subject to UTF8 also fixes the NLS::getCharset() 'bug' I noticed earlier. Since the subject is already UTF8 there's no need to have that function return ISO-8859-1 The modified line in mailbox.php simply has to look like: $msg['subject'] = utf8_encode($imp_ui->getSubject($ob->subject)); Sat, 15 May 2010 16:02:52 +0000 https://bugs.horde.org/ticket/9020#t58837 As it turns out, the issue was only half fixed - not sure why. Some messages were now showing fine while others still had question marks. I started looking and finally traced it down to: imp/lib/IMAP/MessageCache.php where the function retrieve that gets the subject ( and other header pieces ) says... : // There should not be any 8bit characters here. If there // is, we either need to convert from the default charset // or replace with question marks. The line that verifies if I have a default charset is this: if (!empty($GLOBALS['mime_headers']['default_charset'])) { but my default_charset was empty even though it was setup in imp/config/prefs.php - not sure why. This is a stock installation of the latest Horde Webmail Groupware edition. I simply added above that line, the following: $GLOBALS['mime_headers']['default_charset']="US-ASCII"; and now finally all the subjects are showing fine. The two issues were: #1. UTF8 encoding in the subject line #2. missing default charset in IMP Sat, 15 May 2010 17:24:08 +0000 https://bugs.horde.org/ticket/9020#t58838
