utf8

[Denise Chemla]

Hi everybody,

 

I am french, I use intensively gnu-emacs but I don't know it too much. I probably click on bad keys from my keyboard and now, each time I want to save my file using ctrl-s, emacs tells me something like "please confirm your encoding is well utf-8-unix" and only after I write all the letters U T F - 8 - U N I X, it saves my work. I am completely tired to type all those letters at each time I save.

 

Could you help me, telling me what I made wrong ?

 

Sincerely yours,

Denise Chemla

That cannot work! C-s is bound to incremental-search- or isearch-forward.

You should check the environment variables LANG and LC_ALL. They make GNU Emacs choose an encoding that corresponds to their values. It might work to override this setting by using in your init file

	(prefer-coding-system 'utf-8)

BTW, you don't need to repeat the letters "U T F - 8 - U N I X", the second and the other times you can use the arrow keys (up or down) to get your preferred value back. TAB also allows to expand the word started.

Maybe you have some characters in your text which aren't recognised. Got this sometimes from copy-and-past mailings.
Check the text if something isn't displayed correctly.
If this is the case, correct theses letters.

UTF8

[David Rasmussen]

When I just do

'emacs whatever.txt'

and edit the newly created file using some danish special characters, 
and then save, I get an ISO-8859-1 encoded text file. How do I get emacs 
to use UTF8 instead of ISO-8859-1 as default?

Do `C-x RET f utf-8' in the buffer.  If you always want to use utf-8,
you should change your locale.

In emacs? Where do I do that?

If you want all your applications to use utf-8, no.  If you just want
Emacs to prefer utf-8 use `set-language-environment'.

Set LANG to something like en_GB.utf8 (or da_DK.utf8).

If you  only want  that inside emacs,  M-x apropos  coding-system RET.
Check  those  items  with  a  "default"  in the  name.   Then,  do  an
appropriate (setq ...) in your ~/.emacs.


If  you want  Emacs and  other applications  to use  UTF-8  instead of
ISO-8859-1 by default, set  the environment variable LANG to something
like "da_DK.utf8" before starting Emacs and those apps.

But the rest of my system already is using UTF-8,
and my LANG is da_DK.UTF-8. So why isn't emacs
automagically using UTF-8 by default?

I have set it up manually in emacs now, though.

My crystall ball tells me that you're using Emacs 21.2.  It should
work in Emacs 21.3.

Heheh... Emacs says 21.3.1.

If you do:

$ LANG=da_DK.UTF-8 emacs-21.3 -q --no-site-file

Which language environment does `C-h C-l RET' report?

UTF-8. But as I wrote elsewhere, I already have 
set this up in the Mule menu. The interesting 
thing is why it wasn't UTF-8 to begin with.

You're missing the point.

When you start Emacs with '-q --no-site-file' it does not read your
customizations.  So, the reason it didn't use utf-8 is a setting in
one of your init files.

What? What init file?

.emacs, default.el or site-start.el.

Weird. The system was newly installed. I can't 
reproduce it now, even on another new account. My 
best guess is this: I copied my .emacs from my 
cygwin system on a Windows computer. Maybe it had 
a specific line in it, that told emacs to use 
ISO-8859-1. Maybe.

Yep! That's it. I just checked the old cygwin 
.emacs, and it had the line

'(current-language-environment "Latin-1")

where the other has UTF-8.

That's because the utf-8 support in Emacs was considered subpar, IIRC.
In the CVS code, this should not be the case anymore.

to your init file (e.g. ~/.emacs.el) you could add:

(setq load-path (cons "/path/to/utf-8-input_file/" load-path))
(prefer-coding-system 'utf-8)
(set-terminal-coding-system 'utf-8)
(set-selection-coding-system 'utf-8)
(modify-coding-system-alist 'file "" 'utf-8)
(setq default-enable-multibyte-characters t)
(load-library "utf-8-input")
(setq default-input-method 'utf-8-input)

`utf-8-input.el' is available at:

 http://homepages.comnet.co.nz/~r-mahoney/scripts/scripts.html

Of course, seeing the above list, you should think "hmm, all this just to
use utf-8, there must be a better way".
At which point you might discover set-language-environment.

Which is what happened :)

I just did in the menu:
Options->Mule->Set Language Environment->UTF-8

It seems to work.
