861129 - Displays wrong German Umlauts in mails when viewed as Original-Html

Status: RESOLVED DUPLICATE of bug 594646

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Lutz Nevermann]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20100101 Firefox/20.0 SeaMonkey/2.17
Build ID: 20130331213155

Steps to reproduce:

Viewing mails with Seamonkey 2.16 or 2.17 (does not happen in 2.15.2!)


Actual results:

German (actually not only German) special characters are displayed wrongly.
Some examples show how it looks
GrÃŒÃe or für or nötig or hängt or MÀrz or é or „“


Expected results:

Same examples with the right characters look like this
Grüße or für or nötig or hängt or März or é or „“

Funny thing is, there are two different possibilities like ÃŒ or ü for ü depending on the sender.
This does not happen to all mails but only individual senders.
It does not happen in 2.15.2.
It only happens in mails viewed as Original-Html not view as simple-Html or plain-Text.
It's not may stetting Character encoding (tried it).
It's not "Content-Type" nor "Charset" nor "Content-Transfer-Encoding" 

It does not happen in print preview nor print nor forwarding, replying, edit as new.
