Are Polish characters convered by ISO-8859-1?
Is this working with 4.7?

Comment 2

[Katsuhiko Momoi]

It's ISO-8859-2.
MHankus, please attach the source of the problem message
in this bug report.
Also a few questions:

1. Did the display work before this build?
2. What mail program was used to send this message? Mozilla?
    or some other program?

We need the above information to confirm this bug.

1. I'm not sure if it worked before (I have not used Mozilla to send any e-mail).
2. Message was sent from Mozilla. When I send a message from 4.7 the header is
OK even in Mozilla. Problem occurs when i send mail from Mozilla. When I type
Polish characters they appear normally, but when I send a message they are
converted to "?".
  Messages sent from 4.7 are OK, in Mozilla too (Polish characters are displayed
correctly). So i think that problem occurs when I send a message.

Message body is OK.

I think you need to set mail charset to ISO-8859-2. Did you do that before 
sending the mail?

[Mirek Hankus]

no i didn't. Now it works fine. Anyway, in my opinion character encoding should
happen automatically. It works fine for message body, so why it does not work
for messsage header ???  Or eventually it can be configurable from
Edit->Preferences. Menu for choosing character encoding is well hidden (it
appears only when you compose mail, so many people will not find it), but it is
only my opinion. Thanks for help.

We are not doing automatic charset detection for mail send. It is not easy to 
determine accurately (sending out a mail with wrong charset label have to be 
avoided).
You should also see '?' if you send as plain text. Entities are used in case of 
HTML mails so that's why you don't see '?'. So the mail was actually sent as 
ISO-8859-1 instead of ISO-8859-2 (you can check that by using view source).

There is currently a way to set the default send encoding, e.g.
to ISO-8859-2 if you want. Most users use one encoding for mail send
generally and ocassionally need to switch to another encoding. 
The send default setting should take care of this type of needs.
Currently, the send default is set via the menu "View | Character
Set | Set Default Mail Send Character Set". Once this is set, it will
not change until the user explicitly changes it.
In the near future, this will be controlled by a preference
item instead.

marking it verified.
