For issue #2, I found the following by printing the Ascii codes for
each letter of the troubled words in the subject.
Taking for example the word: Académico
When it's being displayed properly, it's made up of the following codes:
65 - A
99 - c
97 - a
100 - d
195 - ?
169 - ?
109 - m
105 - i
99 - c
111 - o
When it's showing incorrectly, it's made up of:
65 - A
99 - c
97 - a
100 - d
233 - ?
109 - m
105 - i
99 - c
111 - o
I got these values by running the following code:
for ($x=0;$x<strlen($msg['subject']);$x++) {
print ord(substr($msg['subject'],$x,1))." -
".substr($msg['subject'],$x,1)."<br>";
}
In one example the é is made from two codes ( 195/169 ) and displays
properly while the second time around it's made from only one code (
233 ) and shows the question mark.
What gives ?
Quoting [email protected]:
I'm still unsure as to what issue #1 is and it still remains but I
did make headway with issue #2.
I tracked down the problem to Horde/Text.php in the function
htmlSpaces(). More precisely, this line:
$charset = NLS::getCharset();
NLS::getCharset always returned UTF-8 even though my subject was
encoded in ISO-8859-1. Further down, this line was effectively
emptying out my subject line whenever $charset was set to UTF-8:
$text = @htmlspecialchars($text, ENT_COMPAT, $charset);
For now, I changed $charset = NLS::getCharset(); with $charset =
NLS::getCharset(TRUE); which works because now the charset is
returned as ISO-8859-1
Is this a limitation of the htmlspecialchars() function ?
However, I still have issue #1 present where it shows '?' instead of
the actual character.
Quoting [email protected]:
I have two problems, not sure if they are a bug on my server or
maybe a bug within IMP.
I am using the latest Horde Webmail distribution:
Horde: 3.3.8
IMP: 4.3.7
c-client library: 2007e
libiconv: 1.13.1
Dovecot IMAP: 1.2.10
Issue #1.
IMP can't display characters from a different charset in the
subject and instead displays a ? instead of the character. In the
body of the message the subject displays just fine.
I enabled the rawlog option in Dovecot to see the actual IMAP
conversation between IMP and IMAP. When it just gets the message
index, for that particular message I see:
* 4 FETCH (INTERNALDATE "11-May-2010 20:22:31 -0400" RFC822.SIZE
2357 FLAGS (\Seen) ENVELOPE ("Tue, 11 May 2010 17:53:34 -0600" {86}
IT-F01 Solicitud de acción de Infraestructura Tecnológica. Otro
según detalle adjunto.
Which is perfectly fine. However, in Webmail I see the subject as being:
IT-F01 Solicitud de acci?n de Infraestructura Tecnol?gica. Otro
seg?n detalle adjunto.
Issue #2.
IMP shows no subject line at all for messages that contain subjects
defined encoded in ISO-8859-1. On the server the subject starts
like this:
=?iso-8859-1?Q?FW:_
What could this be ?
Thank you!
