109867 - Encoding for Subject not recognised if subject string doesn't contain encoding info

Status: VERIFIED DUPLICATE of bug 77903

(Core :: Internationalization, defect)

Description

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.5+)

If a message's header contains the "Content-type:" field and well-defined, but
if the subject doesn't contain the format like  =?big5?B?XXXXXXX=?=   but only
the "raw" codes of characters, Mozilla can't display the subject correctly for
the first time.  NB: the message body is correctly displayed.  When I look at
View > Character Coding, the correct coding is chosen.  If I choose again the
same coding, subject is displayed correctly this time.

Maybe Mozilla needs to go backward to subject once it finds the "Content-type:"
field.
I've a test case for this bug.  It is an email (I've removed personal data from
it) sent from a friend using Yahoo!.  You will see that Big5 is chosen, but you
have to choose the encoding once again to make the subject appear.

Reproducible: Always
