Reproducible: Always

Steps to Reproduce:
1.

3.


Expected Results:  
The same font in every message

I received this message twice (once on a mailing list, once personally). It's a good example.

I often see this, I have the feeling it may have something to do with the encodings...  Can you attach .eml files for both of those?

Comment 5

Hm, is it ok when I just post the Content-Type Header?

From what I see, every "correct" displayed mail has: text/plain; charset=iso8859-1 whereas mails with charset=utf8 for example are displayed wrongly.

If you want to do some experimentation, can you create a folder, put those two messages in it, open the folder with a text editor and change one of them to see if changing the charset makes the difference. 

If the folder is named bug378732 the file you should open is also named bug378732 (no extension). Find it in your profile folder <http://kb.mozillazine.org/Profile_folder>

You were right. When I change the charset from iso8859-1 to utf-8 the mail is displayed using the "wrong" font.

Comment 8

[Magnus Melin [:mkmelin]]

Yeah... it's a bit strange, and I've never seen it on windows.

Comment 9

[Fabian Zeindl]

You mean it's got something to do with fonthandling under Linux?

Comment 10

[Magnus Melin [:mkmelin]]

... or the actual available fonts themselves, yes.
