Note that you have to have your language environment set up correctly
though (you can do this with `M-x set-language-environment').  In many
LEs, typing `C-q 244 RET' will give you character 164 in latin-1, which
is the `currency sign', not a euro sign (latin-1 doesn't have a euro
sign), and looks quite different.

[I can get `C-q 244 RET' to produce a euro-sign if my language
environment is set to `latin-9', but most other language environment
seem to give me the currency sign.]

Hi,

I am following this discussion about the Euro-Sign ... and wonder, how to
produce an Euro sign within a buffer if I have NO Euro key an my keyboard.
I am using a US keyboard and running emacs 21.1.1. on SuSE 8.0

Use one of the input methods that allows a euro sign.
C-u C-\ latin-9-prefix RET selects one of them and `~ e' inserts
then a € char in your buffer.  Or set LANG=de_DE@euro and then
use the Multi_key (which you may have to bind to some key with
xmodmap) and then use Multi_key e = (this should work in all Xwindows
applications, more or less).

Yes, this does the job, great. Now i can insert the €.
Windows users could do

(global-set-key (kbd "\200") 'insert-euro)

to get the € at the same key like in other Windows-programs.

Thanks,

Re: displaying the Eurosign at all

I still have problems with the EURO sign:

This works, e.g. I see a Euro sign in the current buffer. However
there is no Euro sign character (latin-9) in the file, even though my
default language environment is set to Latin-9.

When I insert a EURO character with another editor (for example
SciTE) into a file, then Emacs still shows it as \200.

So, something is still wrong, but what?

To bind a command to the euro key, I'd recommend something like:

  (global-set-key "€" 'insert-euro)

Also instead of `insert-euro' I'd just use:

  (global-set-key "€" 'self-insert-command)

But since "€" is already bound to self-insert-command by default, I'd
recommend you don't change anything at all.

BTW 128 (aka \200) is not the latin-9 encoding of the euro sign (it's 164,
aka \244), AFAIK, so the problem is most likely that you haven't correctly
described the coding-system used by your keyboard, which doesn't seem to be
latin-9.

my keyboard coding-system was set to nil (I use a US keyboard) but
that is not the problem I've encountered. The real culprit is once
again Micro$oft. They are using a modified version of the Latin-1
characterset (WinLatin-1, or whatever one can call it, and that is
what I've been using without knowing for a while now. Using winlatin-1
the Euro sign is on \200. That works fine on e-mail between Windows
systems. I am not sure how to solve the problem in general. I would
expect if I insert \244 in my email, using ordinary Windoze
applications will see some wierd character, but not a EURO sign.

Perhaps emacs on MS-Windows can identify the special keyboard encoding
used there.  Otherwise, 

 (global-set-key (kbd "\200") (lambda (n) (dotimes (i n) (insert "€"))))

should do.

So why do you try to use latin-9?  Just use "winlatin-1" (IIRC it's
actually called windows-1252 or some such).

Latin-9 or ISO 8859-15 has €. ISO 8859-1 and the others do not.

I think it has already been mentioned: windows-1252 has the € at
position #x80.

This message should go out encoded in windows-1252.

Re: displaying the Eurosign at all

[Josef Dalcolmo]

Well, it's not quite that simple - at least not with my NTemacs
version 21.3.50.1

There is no language environment called windows-1252 (though
windows-1255 exists). 

The default terminal and keyboard encoding is indeed cp1252, which
explains why I wasn't having problems with typing and displaying EURO
signs. 

However, when default file I/O is coded in C to be 
default-buffer-file-coding-system = 'iso-latin-1-dos'

Setting this variable to cp1252 did not do the trick either.  I had to
set file-coding-system-alist (I added an entry for .txt to be mapped
to cp1252, and now I can see the EURO sign instead of the \200 when
opening a text file generated under Windows2000 by another
application.)

Modifying (file-coding-system-alist) wasn't trivial, because configure
shows two of the entries to be mapped to functions erroneously as
strings. If I just add something to the list and save it, I get an
error. I guess this is a bug.

I think the default coding system for file I/O under Windows
should be cp1252 (aka windows-1252) or cp1252-dos, not
iso-latin-1-dos. Even better, Emacs should be able to determine the
locally used default encoding and use that as the default (which
varies by localization of the OS).

Since you are using a CVS version, update it to the latest. Or if you
can't: use (require 'code-pages)

Emacs uses the locale environment to determine the default coding
system. (Other than that it should IMO default to UTF-8 and not to
whatever Western (!) European users might prefer if they don't prefer
UTF-8.)

Since this is about a development version of Emacs, we should move
this elsewhere.  See INSTALL.CVS.

Indeed, window-1252 is not a language (I know, there's a "Latin-1" language
environment, but it was just a mistake).  I meant "the cp1252 coding system"
which is also sometimes called "windows-1252".

Good.  But in that case, you shouldn't need the global-set-key binding to
insert a euro.

Assuming all this is with "emacs -q", it sounds like a bug.  Please report
it with M-x report-emacs-bug.

Sounds very odd.  What exactly did you do?  What does
C-h v buffer-file-coding-system say after you load a file with a \200 euro?

As far as I know that's what it does already.
But I don't actually write or use the Windows part of the Emacs code, so
I may be wrong.

Here is what I have in my ~/.emacs:

(when (fboundp 'unify-8859-on-encoding-mode)
  (unify-8859-on-encoding-mode 1))
(when (fboundp 'unify-8859-on-decoding-mode)
  (unify-8859-on-decoding-mode 1))

(setq default-enable-multibyte-characters      t
      unibyte-display-via-language-environment nil)

;; If we got Latin-9 take it:
(setq my-latin (if (assoc-ignore-case "Latin-9" language-info-alist) 9 1))
;; For coding-system we don't specify *-unix to allow it to load DOS files.
(cond
 ((= my-latin 1) (setq my-lenv     "Latin-1"
                       my-encoding 'iso-8859-1))
 ((= my-latin 9) (setq my-lenv     "Latin-9"
                       my-encoding 'iso-8859-15))
 (t (error "Invalid value for my-latin variable.")))

(set-language-environment my-lenv)
(prefer-coding-system my-encoding)


Then I type in € with C-x 8 $ 
and it shows like an euro, and when I load files containing \200, 
they are interpreted as Latin-9 (iso-8859-15) files and these
characters show as euros.

Of course, it helps to have X fonts with iso-8859-15 characters too.
