Subject encoding problem

[deepblue]

Hi,

when I send a Mail to my zimbra account with a subject line containing special characters, which are ISO-8859-1 (or other, like ISO-8859-2) encoded, the zimbra web mail client does not display the subject correcly. The only encoding without that problem seems to be UTF-8.

The subject seems to be correctly encoded:

Subject: =?iso-8859-1?Q?B=C3=BCgelbrett?=

Zimbra webclient displays:

Bügelbrett

There is no problem with the body of the message.

I am running 4.0.4 on REHL4-64
I have installed the compat libraries:
compat-libstdc++-296-2.96-132.7.2
compat-libstdc++-33-3.2.3-47.3
compat-libstdc++-33-3.2.3-47.3 (32-Bit Version)

I have the impression, i am missing something. I have searched the forum up and down and found various threads about header encoding. But none with exactly that problem

Any hints?

Regards
Thomas

Are you running the latest version (4.0.4)? Have you tested with the 4.5 beta? Can you post as an attachment the 'Show Original' result from a message with the problem?

Your subject is not correctly encoded. C3 is à and BC is ¼ in iso-8859-1. The two bytes C3 BC together are ü in utf-8, but your message subject is explictly indicating iso-8859-1, and that's what it's being decoded as.

You are so right!

I sent the mail from a broken mailer. I doublechecked everything and now zimbra displays the subject correcly regardless of the encoding (ISO-8859-1, ISO-8859-2, UTF-8...)

Thanks a lot

I have the same pb with a 4.5.10 version of zimbra.

Here is the subject that is not decoded :

=?iso-8859-1?Q?Rappel Vendredi 4 avril 18h INVITATION Rugby Club Aquitaine - R=E9seau Entreprendre Aquitaine?=

You're not allowed to have spaces inside an RFC 2047 encoded-word (i.e. between the =? and the ?=). Our current MIME parser enforces this rule strictly. We plan on loosening the rules in the future -- see Bug 20857 - accept spaces in RFC2047-encoded header fields.
