How to add the encoding in the emacs window?

How to add the encoding in the emacs window?

[avilella]

Hi,

I would like to know if it is possible to have the encoding specified
in a given emacs window:
when I open emacs with GNOME, the window specifies something like:
"emacs -- myfile.ext"
and I would like to have the window name being for example: "emacs
UTF-8 -- myfile.ext"

Thanks,

    Albert.

No. The encoding is a property of the buffer. It's shown at the  
beginning, the left-most edge, of the mode-line. You can select with  
the mouse cursor that symbol and a *Help* buffer will explain what  
the encoding is.

If you mean how to set an encoding preference for GNU Emacs, you  
might start with setting environment  variables like LC_CTYPE. From  
its value GNU Emacs will set an internal preference for buffer  
encodings – but it won't be strict since internal settings (like file- 
coding-system-alist, network-coding-system-alist, process-coding- 
system-alist, auto-coding-alist ...) pre-define a lot.

You can go further and put into your user init file code that reads  
LC_CTYPE (or a synthetic environment variable of your own) and then  
modifies such lists, and which also emits a

	(prefer-coding-system '<some value>)

There are also buffer local variables which can be added at the top  
of the file or its bottom. Examples for top:

	;;; -*- mode: Emacs-Lisp; coding: utf-8; -*-

and bottom:

	%%% Local Variables:
	%%% mode: latex
	%%% TeX-master: t
	%%% coding: utf-8-unix
	%%% TeX-command-default: "XeLaTeXx"
	%%% End:

(setq frame-title-format
      '("Emacs "
        ;; Or try "%Z", coding system mnemonic (cf. mode line)
        (:eval (symbol-name buffer-file-coding-system))
        " -- %f"))
