However Thunderbird 0.9 doesn't appear to unwrap. I've noticed a fair amount of e-mails to me now have these weird chars half-way through the Subject line (directory pane). If I double-click on that message to bring it up into its own window I then see "this is the text" - where that whitespace might be "\s\t". Reproducible: Always Steps to Reproduce: 1. Create by hand an e-mail with a Subject header with a continuation line 2. e.g "Subject: this is a\ttest" 3. view in Thunderbird Actual Results: See "this is a[X]test" in directory pane, and "this is a test" in message pane. Expected Results: Should have said "this is atest"? Confirmed that Outlook views it as "this is atest" - i.e. the tab was removed as it was a continuation char.
I can confirm this on Linux Thunderbird 0.7.3 (20040819). According to RFC2822 section 2.2.3, a newline followed by whitespace should be removed. The whitespace itself should NOT be removed. However, certain other software seems to think that <newline><tab> should be replaced with <space>. When Thunderbird displays such a message, it correctly displays the tab as a small space in the message pane. But in the message list, it incorrectly displays an "NL" placeholder. This does not happen with lines properly wrapped using <newline><space>, such as are generated by Thunderbird itself.

Confirming. I see this with TB 1.0 on windows XP. When a subject line is wrapped in the message source, and the continued line is indented with a tab character, the tab appears in the message list pane as a little filled rectangle. When I double-click on the message to open it in a separate window, the title bar of the window (based on the message subject) contains a little rectangle for the tab character. In the subject line of the preview pane or of the separate message window, the tab appears as a wider-than-normal space. The wider-than-normal space effect can also be reproduced in a trunk copy of TB for solaris/gtk2, though the other two effects don't appear.

Seamonkey bug 240924. (In reply to comment #0) > Expected Results: > Should have said "this is atest"? As noted in comment 1, this is not the expected result; the whitespace is supposed to remain.
It's failing (Mozilla 2005022009 Mac OS X) even if it's just a space, not a tab. If there's one space (which is how Mozilla itself breaks lines) then it appears as three spaces in the thread pane and composition window, but only one space in the header of the message pane. Should we make this part of this bug?
IMVHO, in this very specific case Thunderbird could break the RFC just a little and convert such tabs to spaces, because: 1) tabs in subject lines don't do much sense anyway, 2) those black boxes are ugly, and 3) almost everyone else use tabs to indent folded lines, because a) in just about all other fields, tabs and spaces are equivalent, and b) it increases readability.

I'm using Thunderbird 1.5. The little rectangles still appear and make Thunderbird look unfinished and unprofessional. Please convert these tabs characters by spaces as suggested by Magnus.

I am seeing this problem using Thunderbird 1.5.0.5 on Windows XP. In my case, mailman is what is indenting the wrapped subject lines with TAB characters. mailman is very popular software! Here is a dump of an example message header: 0002020 C c : sp nl S u b j e c t : sp [ B 0002040 u i l d b o t ] sp B u i l d B o 0002060 t sp S U C C E S S nl ht ( B l d _ 0002100 g s s d k _ g s s d k _ t e s t 0002120 _ 2 0 0 6 _ 0 9 _ 1 2 _ 0 0 _ 0 0002140 1 _ 0 0 _ I n c r e m e n t a l 0002160 _ 2 ) nl X - B e e n T h e r e : Given this issue still exists in Thunderbird 1.5.x, should the bug's version field be update to make this bug appear relevant?
*** Bug 331137 has been marked as a duplicate of this bug. ***
Me too. This bug leads to the odd case that when you cut and paste the subject line it does not match the subject line. Converting to a space would not violate the principle of least astonishment, IMHO.

I have some messages with autowrapped subject and in which <nl><tab> should be removed and not replaced by a space. I don't know what the software is, but I have this line in the headers: X-Mailer: Internet Mail Service (5.5.2657.72) I hope it helps.

At the dupe, reporter notes that the odd character displays also in the preview text in the new message alert.
Not sure why RFC 2822 was recommended before, but RFC 822 is the one usually used for email standards. Its section 3.1.1. "LONG HEADER FIELDS" talks about multiple whitespace characters being allowed, but does clearly state that the whitespace character should be honored during unfolding. However, the pictogram version of the tab character (a right-arrow in my case) that I see in TBird is really annoying, and given the prominent use of tabs in header fields to indent "for looks" I would personally like see Thunderbird be consistent and display them as a single space in the list view like it does in the message preview pane and "view" window.
(In reply to comment #20) > Not sure why RFC 2822 was recommended before Probably because the third line in 2822 is "Obsoletes: 822"
That would be a good reason. :) Either way, my understanding of this ticket is mainly that there is inconsistent behavior in TBird. The list displays the tab character visually as either a full tab or (in my case) an arrow character, and the message panes just treat it as any other old whitespace.
if i remember david correct, the message pane uses a slightly different source for the subject - semi related to bug 172104. perhaps these bugs could be fixed at the same time?
Wow this bug is ancient. It can't be that hard to fix; I mean it's just a header parser fix to strip out the \n\t. I can confirm that it is still annoying me in 2.0.0.6.
It might be fruitful to update in particular the 'version' label for the bug not to be ignored as out-of-date.
I can confirm another 800 users it's annoying (2.0.0.6) It's even more annoying because we have mailman, and typically have longer Subject lines. Please update the importance of this issue so it gets some attention! It's been years!
Using webkit now, this long-standing annoyance is no longer a problem... ;)
Still in 2.0.0.17. However this bug doesn't break threading view, even with subjects without the tab character, thank goodness. Perhaps someone can just make a plugin to strip the subject?
FWIW, the same happens when you want save an attachment with a long, folded filename, e.g. Content-Disposition: attachment; filename="this_is_a_very_long_filename_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx_xxx _xxxx_xxxx.xxxxxx.image" instead of stripping the tab, the file is saved as "this_is_a_very_long_filename_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx_xxx<tab>_xxxx_xxxx.xxxxxx.image", which makes no sense whatsoever... I really hope this get's fixed soon...

It is still here in thunderbird 3.0.3, though instead of showing the bad glyph trying to print the hard tab, the thread view just removes the tab, smashing the words before and after together. It should replace the tab with a space, which is what happens when you open the message in its own tab.
Good Grief, how many years until this is fixed?

(In reply to comment #32) > It is still here in thunderbird 3.0.3, though instead of showing the bad glyph > the thread view just removes the tab, smashing the words before and after together. It's Bug 553280(I dupe'ed to Bug 593337)/Bug 593337 for new phenomenon at thread pane with Tb 3.0(and Tb 3.1). See Bug 593337 Comment #15 for check result with trunk builds(Tb 3.2pre/Sm 2.2pre). Next can be said. 1. This bug never occurs at thread pane after Tb 3.0(fixed by Tb 3.0), because Tab is removed upon Subject display at thread pane. And, by Tb 3.0, Bug 553280/Bug 593337 is generated. 2. Bug 553280/Bug 593337 is fixed by Tb 3.2pre/Sm 2.2 pre. (In reply to comment #29) > FWIW, the same happens when you want save an attachment with a long, folded > filename, (snip) For "Wrong Tab for folding at mid of name/filename parameter value", see Bug 593337 Comment #14, and open separate bug if you believe it's still big problem, please. jh.mozilla@plonk.de, please keep "one problem per a bug".
Thank you!!! I've seen that this appears to be fixed in TB 3+ (on Linux). I really appreciate you addressing this issue. Sweet!
Closing as WORKSFORME.
