Change encoding

Change encoding

[Christophe Jorssen]

Hello all,

I'd like to know if it is possible to change the encoding of a buffer. 
For exemple, my buffer is encoded in ansinew and I'd like to recode it in 
utf-8.

And, by the way, is it possible to "read a file with this encoding", that 
is automatically convert the encoding of a file when opened (say the file 
is encoded in ansinew and I'd like to have it in my buffer encoded in 
utf-8).

I'm using 

GNU Emacs 23.1.50.1

(emacs-snapshot), under unbuntu.

Thanks a lot and sorry for my complete ignorance of the subject.

Look into the Options menu -> Mule -> Set Coding Systems!

File local variables can set an encoding:

	Comment mark(s) -*- mode: LaTeX; coding: utf-8; -*-

in the first six lines of the file (I think) or at the end:

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

'%%%' is the set of three TeX comment marks.

Type "C-x RET f utf-8 RET", and you are done.

No, it's not possible.  Emacs by preserves the encoding of the
original file, and it's easy enough to do what you want with the
command I show above.

Of course, you could also easily enough write a replacement for
find-file which does what you want automatically: change the value of
buffer-file-coding-system after you visit the file.

open the file, then call set-buffer-file-coding-system, then type the
encoding system you want. Type Tab to see a list of possible values.

this page might help:

• Emacs and Unicode Tips
  http://xahlee.org/emacs/emacs_n_unicode.html

you could also run a lisp program that changes all your files in a dir
to utf-8 or any other encoding. you could do this in python or elisp.

For python, see:

• Converting a File's Encoding with Python
  http://xahlee.org/perl-python/charset_encoding.html

for elisp, see:

• Emacs Lisp Examples
  http://xahlee.org/emacs/elisp_examples.html

look for the section to-unix-eol there.
You'll need to change the line

(set-buffer-file-coding-system 'unix)
to
(set-buffer-file-coding-system 'utf-8)

on linux, there's a command line tool iconv that does this as well.
Java solution is also there linked in the python page above.
