318450 - Non-Ascii characters subject displayed in weird chars in Message List

Status: RESOLVED INVALID

(Thunderbird :: Mail Window Front End, defect)

Description

[Max Nokhrin]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5

When the message subject is non-encoded using the ?charset=subject, but instead is written in the non-Ascii charset, the subject is not displayed properly. For example:

Subject: У Вас новое письмо на PM ( From Поиск MP3 музыки )

(The subject above is in Russian, charset is windows-1251.)

This subject appears as weird characters in the Message List. I can provide a screenshot.

I know that this is probably not correct behaviour on the sender's part, but I think that this is something that Thunderbird should excuse and work around.

Reproducible: Always

Attachment: The actual text as it is in the email message (from view source)

This image shows what the message subject (and from field) should actually contain. The text is in Russian. I've cleared out the email address for privacy.

This is expected behavior when the headers are not properly MIME-encoded.  If you right-click the folder, select Properties, and set the default charset to windows-1251, the header should appear as you expect; however, that message is technically illegal.  Bug 140588 is about this same symptom; see also bug 46362.

I agree that it's an error on the sender's end, but I don't agree with Thunderbird's policy to refuse to work around things that will help the users.
