600178 - Problem on display an e-mail writen in Greeks (with html5.enable=true, iso-8859-7 data is converted to utf-8, then Content-Type: charset=iso-8859-7 is applied to the converted utf-8 data)

Status: RESOLVED DUPLICATE of bug 571704

(MailNews Core :: MIME, defect)

Description

[nas]

User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:2.0b7pre) Gecko/20100927 Firefox/4.0b7pre SeaMonkey/2.1b1pre
Build Identifier: Mozilla/5.0 (X11; Linux i686; rv:2.0b7pre) Gecko/20100927 Firefox/4.0b7pre SeaMonkey/2.1b1pre

there is a problem with Greek characters when I see an incoming mail. It appears like the charset isn't correct. I tried to change it from View -> Character Encoding from iso8859-7 to UTF-8 and windows 1253 without any luck. When I send an e-mail to myself ( using seamonkey ) I didn't have any problem reading it. Here there are a part of headers/ email that I believe it will help:
From the " bad read " email: 

--------------------------------------------------------------------------
X-MSMail-Priority: Normal
X-Mailer: Microsoft Windows Mail 6.0.6002.18197
X-MimeOLE: Produced By Microsoft MimeOLE V6.0.6002.18197
X-EsetScannerBuild: 7679

This is a multi-part message in MIME format.

From the " good " email that I send it to myself:

Content-Type: text/plain; charset=ISO-8859-7; format=flowed

Ελληνικά!

In stable versions I don't have any problems to read these e-mails.

Reproducible: Sometimes

Steps to Reproduce:
1. Try to read e-mails with Greek text inside, maybe e-mails send by MS outlook
2.
3.
Actual Results:  
non readable e-mail Greek text

Expected Results:  
readable e-mail Greek text

nas, can you check with html5.enable=false?

Comment 4

[nas]

thank you for your suggestion Wada, ( ありがと　ございます !) ,

when I set html5.enable = false I could read the Greeks from the e-mail that I couldn't - the one on the screenshot!
When I set it back to true , I couldn't. 

Is that something fixable ?

Philip Chee, regression window of this kind of problem is already apparent in other bug - when html5.enable=true is defaulted, and simple workaround is already known by other bugs - html5.enable=false.

Above Greek chars are written in utf-8 in this bug. If this bug is shown with View/Character Encoding/iso-8859-7, glyph like next is shown and is same as you screen shot.
    Ξ�   Ξ±   ΞΉ   Ξ½   ΞΏ   Ο�    Ο�   ΞΉ   ΞΏ

In screen shot, Content-Type: multipart/alternative; is seen.

With which View/"Message Body As" did you get the scrren shot?
Is there text/html part in the multipart/alternative mail?
If yes, does <meta> tag of http-equiv=Content-Type and content="text/html; charset=iso-8859-7" exists in HTML source of text/html part?

Phenomenon/problem depended on View/Message Boy As. As it's still unclear in this bug, tr-open.

No additional information from bug opener for mail data...
Closing as dup of bug 571704 again.
