No "Content-Type:"

No "Content-Type:"

[Shigeki Uno]

Hi, I'm sorry to ask same question again.

I asked you about *Content-Transfer-Encoding* topic the other day and
No problems occured about Encoding MIME e-mails after that.  
(Thanks, Yamaoka-san.)

*But* I said that some e-mails causes *unintelligible sequence of
characters* and these e-mails are encoded by Quoted-Printable.  
I looked into them carefully today again and found that I made an error 
in reports. :-(
  
Following example is e-mail's headers which causes *unintelligible 
sequence of characters*(This is one of them).

I found *Content-Type: text/plain; charaset="iso-2022-JP"* line doesn't
exist. And others which cause *unintelligible sequence of characters*
also doesn't have *Content-Type* line. 

I can read it with _MEW_(Message in the Emacs World) without any problems
but, on the other hand, certainly can't read it with (P)Gnus :-(.  SIGH.

Any suggestions ? 

Thanks.

The only thing I can think of is to use `e' to edit the article to add
the missing Content-Type header.

Maybe it would be nice to have a function which allowed you to view a
message as if it had a specific Content-Type header.

You mean about the traditional japanese mails, I think.  The body has
japanese plain text (iso-2022-jp, 7bit), but the header does not have
no indicators for it.
The user option `gnus-group-charset-alist' helps such messages only
for news:

(defcustom gnus-group-charset-alist
  '(("^hk\\>\\|^tw\\>\\|\\<big5\\>" cn-big5)
    ("^cn\\>\\|\\<chinese\\>" cn-gb-2312)
    ("^fj\\>\\|^japan\\>" iso-2022-jp-2)
    ("^tnn\\>\\|^pin\\>\\|^sci.lang.japan" iso-2022-7bit)

[...]

but is does not work for mail groups.  So far I don't know how to fix
the problem.  Does anyone?

By the way, T-gnus or other Semi-gnusae can do that.  It is controled
by the variable `default-mime-charset'.

I also have had problems with malformed messages before.  Often I can
fix them by using washing functions.  For example, if I received a
quoted-printable iso-2022-jp article with a missing Content-Type
header, I would run the following washing functions:

`W q'  <- This should take care of quoted-printable
`C-u W M c iso-2022-jp RET' <- This should take care of the encoding

I gave it a try before but it was in vain.

I'd be surprised if it only worked for news.  The regexes given here
only work for news, but there's nothing stopping you from having a
regex "^nnml:foo" in there...

Thanks to Kai, it really works.  Well, the method name is stripped
from `gnus-newsgroup-name' in the function
`gnus-summary-setup-default-charset', so we should set the value like
follows:

(setq gnus-group-charset-alist
      (cons '("^some\\.japanese\\.list$" . 'iso-2022-jp-2)
	    gnus-group-charset-alist))

Sorry, the correct way is below:

(setq gnus-group-charset-alist
      (cons '("^some\\.japanese\\.list$" iso-2022-jp-2)
	    gnus-group-charset-alist))

Yep.

I know this lisp...

I'm disappointed...

I'll consider it to use T-gnus. ;-) 
(I used to be a user of semi-gnus. Semi-gnus is suitable for Japanese
Internet users, I think. But I'm not familliar with it , though.)

Thanks.

Solved (was: Re: No "Content-Type:")

[Shigeki Uno]

WOW. Filnally I've just succeeded in decoding unintelligible sequence of 
characters !!

'C-u W M c iso-2022-jp RET' works great ! I deeply appreciate your help.
And also I have to say thanks, Yamaoka-san and Kai.
