Description

9 years ago
For the last several months, certain UTF-8 messages, which are reported as windows-1255 or iso-8859-8-i and have both plain text and HTML parts (these may be sufficient rather than necessary criteria), are no longer properly decoded when forcing the charset to UTF-8. 

Moreover, sometimes one even gets parts of the HTML itself, e.g. the doctype string, in the decoded message.

This happens, of course, with and without my BiDi Mail UI extension.

This started happening between 2009-07-09 and 2009-07-12.

There are no Windows builds between 2009-07-09 and 2009-07-12 so I can't pinpoint the exact day.

Another note: The windows-1255 decoding result also differs before and after the regression, it's not just the post-coersion decoding.

Simplified testcase.

It turns out you don't need the text MIME part. But if you only have text instead of HTML with the same issue (UTF-8 reported as windows-1255 or 8859-8-i), the problem does not manifest.

Bug does _not_ manifest with a clean profile using the same mail folders as the dirty one. But it _does_ manifest with a clean profile into which I've copied my prefs.js, addressbook, bookmarks and cookies, and using the same mail folders.

Manifestation seems to also be affected by the choice of View Message Body as Simple HTML/Original HTML. With some messages I see manifestation with Original and Simple HTML but not with text; with other messages, it's just Simple HTML.
