article editing oddity

[Vladimir Volovich]

Hi,

i've got a message which was in windows-1251 encoding, but
Content-Type header said that it was in koi8-r, so the message was
unreadable.

I pressed C-u g e, and changed "charset=koi8-r" to
"charset=windows-1251" in the Content-Type header.

Then i pressed C-c C-c

But the saved article still contained "charset=koi8-r" !

What's going wrong? AFAIR, this worked with older gnus versions.

	Best regards, -- Vladimir.

P.S. windows-1251 is defined in my .emacs file by

(codepage-setup 1251)
(define-coding-system-alias 'windows-1251 'cp1251)

Uhm.  `C-c C-c' after editing the message will create brand new
Content-Type headers.  And since Gnus thought that the text was
koi8-r, Gnus put that in the new header.

*sigh*

Anyway, `C-u W M c' will let you re-interpret the message using a
different charset.

How about not rebuilding headers if the article is shown by `C-u g'?

Or not reuilding headers when check in by `C-u C-c C-c'?

I don't think this works, unless press `C-u g C-u W M c', since it
washes an article in the article buffer, where characters have been
decoded by (wrong) charset, then the result is double-decoded,
i.e. `\201's shows.

Even `C-u g C-u W M c' does not decode subject and other headers.

*sigh*

My unofficial solution is advicing gnus-summary-show-article. When
number argument comes, pick a charset from predefined charsets or
minibuffer, set gnus-newsgroup-charset and
gnus-newsgroup-ignored-charsets, then ad-do-it.

If this solution is acceptable, I can patch the
gnus-summary-show-article, and maybe a little work let gnus ignored
all charsets.

Yes, that sounds like a good idea.

FAQ: show an article with a specified charset (was: Re: article editing oddity)

[Shenghuo ZHU]

Q: How to show an article with a specified charset?

A: Suppose you want to show an article with charset cn-gb-2312. Use
   `C-u 0 g cn-gb-2312' in the summary buffer. 

   You can also use `C-u 1 g' if
    (setq gnus-summary-show-article-charset-alist 
            '((1 . cn-gb-2312) 
              (2 . big5)))

(Only applied to Gnus 5.8 or greater version)

I've added this info to the manual.
