286551 - A single character (multibyte) split across two encoded words (RFC 2047) in the mail header is not decoded

Status: RESOLVED DUPLICATE of bug 493544

(MailNews Core :: Internationalization, enhancement)

Description

[Donny]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050222 Firefox/1.0.1
Build Identifier: version 1.0+ (20050316)

The seder header has my name with some Lithuanian chars. Those are shown
correctly in gmail and Oulook( Express) but Thunderbird seems to missunderstand
a part of the UTF-8 encoding.

Reproducible: Always

Steps to Reproduce:

Attachment: How I see it in Thunderbird

There are two emails... first one is the one with Lithuanian chars shown wrong
and second one (on the top) is email sent to myself with the first one attached
to it. I wanted to see if those chars would be shown wrong when email was
inlined.

That's the email with Lithuanian chars shown wrong

The name in the header has somehow been encoded as two RFC-2047 encoded words,
with a utf-8 multibyte sequence split between the two.

=?utf-8?Q?Ma=C4=8Di=C5?==?utf-8?Q?=ABnas?=

Technically this is invalid, (but maybe we want to be tolerant?):
   Each 'encoded-word' MUST encode an integral number of octets.  The
   'encoded-text' in each 'encoded-word' must be well-formed according
   to the encoding specified; the 'encoded-text' may not be continued in
   the next 'encoded-word'.

Bug 227290 is a similar issue.

I'll see if it's possible to be tolerant.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.

FYI: Squirrelmail creates headers like this.
