Description of Problem:
Mail header isn't encoded by charset USER choised.
 (but when OS default charset changed from UTF-8 to eucJP)
 (in body, messages are encoded correctly by charset USER choised.)

when I send a message in japanese, outlook express 6 can't understand 
correctly.
(I've already read bug 242549, 24026, 44991 and so on.)

OS version is Fedora Core 1 linux (evolution version is 1.4.5. this is 
provided as a RPM binary file by Fedora).

Default charset is ja_JP.eucJP.
(I changed it from ja_JP.UTF-8 to ja_JP.eucJP because of some application's 
problem.)



Steps to reproduce the problem:
1. run an evolution from application menu 
2. compose a new message(I wrote a message in Japanese. [subject and body])
3. send a message (the body and header charset are iso-2022-jp).
and then, when some user recieve a message by using OE6. that software 
can't understand UTF-8.


Actual Results:
header isn't encoded in the charset USER selected.


Expected Results:
Evolution mailer sends to message in a charset USER selected.
(Despite OS default charset, evolution can send a mail in a charset USER 
selected.) 


How often does this happen? 
always(but when I changed OS charset from UTF-8 to eucJP)


Additional Information:
When I run the evolution from terminal like this,
 $ LANG=ja_JP.UTF-8 evolution
this problem doesn't happen.
(of course, now I wrote alias evolution=... in .bashrc.)
but I would like to do it.
