66757 - German umlauts get displayed wrong

Status: VERIFIED DUPLICATE of bug 70525

(MailNews Core :: Internationalization, defect)

Description

[Oliver Klee]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; m18) Gecko/20010125
BuildID:    2001012504

Reproducible: Sometimes, not very often

Steps to Reproduce:
1. View a message that has German umlauts in the body.

Actual Results:  The umlauts in the message get displayed wrong, e.g. "ü" gets
displayed as ü.

Expected Results:  The umlauts should get displayed correctly.

Opening the message in a new window or relaunching mozilla leads to correctly
displayed umlauts.

_Which_ messages are displayed incorrectly and _when_ it occurs seems to be
random. Most of the time it is ok.

This bug seems to be a regression. I started seeing it maybe a week or two ago.

I have seen this, too, but I thought the character set wasn't specified
correctly (but I didn't look it up).  Could you attach the complete mail
header of a message showing this?

Comment 2

[Oliver Klee]

I'll do so when the bug shows its ugly head again. But as far as I understand
it, it is not message-specific. When it happens, it seems to happen to all
messages with umlauts in them. At other times, those messages display just fine.

Ok, here's the header + start of mail that is displayed wrong:

Liebe Mitglieder und Gaeste des Fakultaetentags,

endlich kann ich Ihnen die (fast-endgueltigen) Statistiken des 
=46akultaetentages zusenden; neben Verzoegerungen bei einigen 
"Datenlieferanten" hatten wir groessere Engpaesse im Sekretariat, die 
hoffentlich ab 1.2. endgueltig behoben sind. Ich bitte Sie daher um 
Verstaendnis.

Alle "Datenlieferanten" bitte ich um �berprüfung und ggfls. Ergänzung bzw.
Korrektur der Einträge, insbesondere die Frauenanteile sind nach wie vor auch
in vergangenen JAhren unvollständig.

I forgot the part of the original message text with the umlauts in it:

bzw. Korrektur der Eintr=E4ge, insbesondere die Frauenanteile sind nach

Marking NEW as per comments.

Comment 6

[Oliver Klee]

Ok, tested a bit more:
* When the bug occurs, all messages with umlauts in them are displayed incorrectly.
* Closing and re-opening MailNews or opening the message in a separate window
gets the umlauts do display ok.

Changed the component to i18n and reassign it to nhotta.

>* When the bug occurs, all messages with umlauts in them are displayed
>incorrectly.

Is this always reproducible or is there any procedure make this to happen?

Comment 9

[Oliver Klee]

I still don't have an inkling about what triggers the bug. So I cannot reproduce
it reliably, sorry.

Oliver Klee, please attach the entire message rather
than a part. Your test case of:

------- Additional Comments From Oliver Klee 2001-01-27 18:29 -------

is supposed to be multipart mized but it contains one part.
It is hard to judge whether or not missing part plays a role
in this bug.
In any case, your test does not cause a problem with 2/5/2001 
Win32 build on NT4-US. Maybe your platform has something to
do with it, i.e. Win 2000. But without a complete test case,
it is hard to tell. 
Rather than copy & paste the message, make it into an attachment.

I couldn't reproduce it with 2001-02-05-08-mtrunk linux build either.
[e-mail] has posted a test message in newsgroup
netscape.public.mozilla.qa.i18n
Oliver, could you check that message with the latest build in your environment?
Thanks.

With the 2001021304 trunk build, I haven't seen this bug so far. Marking
WORKSFORME. I'll reopen this bug and attach a test case if I see it again.

Comment 14

[ji]

Marked it as verified. It's not happening on 02/19 mtrunk builds.

Comment 15

[Oliver Klee]

Reopening as I'm seeing this again on 2001031204 (after one month without seeing
the bug). The test message by Naoki Hotta now looks like this:

Essen aus der Dose steht nicht gerade in dem Ruf, ein kulinarischer Höhepunkt
im Kochtopf zu sein. Die Site räumt mit dem Vorurteil auf: Witzig und
informativ - alles zum Thema Dosenfutter.

Yesterday, this build displayed umlauts fine. I still don't have a clue what is
triggering this behavior.

This could be a dup of bug 70525.

Comment 18

[marina]

this is a dup of 70525. Oliver , this happens after you switch folder from the
account central, i did see the umlauts turn into two single bit chars and it is
not a random problem, just depends on when you actually opened the mail: if
after switching from account central then you'll see mail body garbled .
Restart, go directly to the mail and you'll see mail body displaying correctly.
It is an annoying problem and it is described in 70525.
