Mails with subjects like Subject: Grattis =?UNKNOWN?Q?p=E5_f=F6delsedagen!?= gets shown with the wrong character set.

Naoki, do you know if this is a legal syntax?

I think this is a similar problem as bug 71541 (or a dup). cc jgmyers, momoi

This is the same as bug 71541, except where that bug covers the label "UNKNOWN-8BIT" but this bug specifies the label "UNKNOWN". The label specified in the relevant MIME standard is the former, though it would be legitimate for Mozilla to also accept the latter. Alternatively, it would be a legitimate approach to treat all unrecognized charset labels as being "UNKNOWM-8BIT". Marking this bug as depending on bug 71541.

I think this is the same as bug 77903.
