set input/output coding system for term-mode

set input/output coding system for term-mode

[William Xu]

How can i set input/output coding system for term-mode inside emacs? The
only way i can think of is starting emacs as `LC_ALL=coding emacs',
which is far from satisfactory.

If you mean keyboard input and screen output, then the commands you
want are "C-x RET k" and "C-x RET t".

What about "C-x RET c" stands for change the coding system for following
command? Then start the term mode.

   If you mean keyboard input and screen output, 

Firstly, I have (prefer-coding-system 'utf-8) in .emacs. In *terminal*
buffer, suppose there's a file `foo' encoded with 'gb2312, at present
`cat foo' would display garbages, which is what i'm trying to solve.

   then the commands you want are "C-x RET k" and "C-x RET t".

Hmm, it has no effects. Just same as previous.

Doesn't work either..

It does not work in any physical or emulated terminal to see the  
contents of a file which is not encoded in the terminal's default  
encoding in the file's proper encoding. Except this contents contains  
ANSI sequences to switch between character sets or writing directions.

The question is why you want to do such a silly thing in GNU Emacs!  
You can easily visit the file in some buffer using the correct  
encoding ... And you can prefer a few coding systems.

So you mean that the terminal's default encoding can't be changed inside
Emacs?

Hehe.. Actually i'd like to use terminal to login some BBS system(by
ssh). Any better alternatives?

Use more than one *shell* or *terminal* buffer – each with a  
different encoding, suiting the BBS.

   each with a different encoding,

Isn't this my original problem?

No – as far as I understood. You wanted to change the single buffer's  
encoding "on-the-fly," having in it segments in encoding a or  
encoding b or encoding c or ...

Check whether there is a hook that can set the encoding for a *shell*  
or *terminal* buffer when it is created and give it a unique name, too.

It doesn't matter whether it can be set "on-the-fly" or not. i will
simply have one single *terminal* buffer. *terminal* has a
term-setup-hook, i add the following to it:

,----
| (defun xwl-term-setup-hook ()
|   (set-buffer-process-coding-system 'gb2312 'gb2312)
|   (set-buffer-file-coding-system 'gb2312 'gb2312)
|   (set-terminal-coding-system 'gb2312))
| 
| (add-hook 'term-setup-hook 'xwl-term-setup-hook)
`----

But still without luck..
