1028531 - UTF-16LE emails are encoded in UTF-8, although _charset_ declares UTF-16LE in the mail

Status: RESOLVED DUPLICATE of bug 961983

(Thunderbird :: Message Compose Window, defect)

Description

[Praveen A]

Attachment: test utf-16LE.eml

+++ This bug was initially created as a clone of Bug #615595 +++

This happens when you reply to a message encoded as UTF-16LE. The email metadata mentions characters as UTF-16LE, but it is actually encoded as UTF-8. So the message content has many chinese characters instead of its actual content. When encoding is selected as UTF-8 manually, it is shown correctly.

UTF-16LE should never be selectable as an outgoing encoding for e-mail. MIME can't handle those messages encoded in ascii-incompatible encodings.

That will be prevented in bug 1003716, but that's not on target for 31.

I am curious why this is labeled critical.  Does this make Thunderbird unusuable?

Comment 4

[Praveen A]

Wayne, yes unless you expect users to be able to read chinese characters. I was unaware of the bug and I was scratching my head when all my friends asked me why I was sending them chinese email. The mail I replied to was sent by google drive when someone shared a document with me. So it is very likely to affect many people.

This above bug is fixed in 36 and thus in https://www.mozilla.org/en-US/thunderbird/all-beta.html
Praveen, Is it now resolved for you?
