Ciao a tutti,

eamcs 23 from  debian unstable on terminal does  not show correctly euro
sign showing instead something like a little "star".

The other characters are shown correctly.

What could I check?

Environment variables like LANG or LC_CTYPE or LC_ALL. Make them  
based on ISO Latin-9/ISO 8859-15 or Unicode (UTF-8).

the font used by your terminal. and perhaps your locale settings.

Put point before the euro sign and type `C-u C-x =' to see the font
used to display it.

Type "M-: (terminal-coding-system) RET" and see what it displays.

I set only LANG variable:

LANG=it_IT.UTF-8

Obviously you're using something that converts EURO SIGN (at U+20AC)  
to CURRENCY SIGN (at U+00A4). Launch GNU Emacs with the option -Q and  
see whether it can display EURO SIGN without your and your system's  
customisation (that "display table") correctly.

Yes,  it  works correctly  showing  the euro  sign:  what  could be  the
problem?

As statement in your system's or your own init file. By launching GNU  
Emacs with -q you can check, whether it's the system's one: if you  
still see the €, then it's not the system's init file which converts  
it to ¤. I already gave you a hint: "display table." I don't use any,  
so I can see € and ¤.

If this does not help, bisecting can. It's a method of commenting one  
half of your init file and launching GNU Emacs. When the error is  
gone, then it's in the commented section. Otherwise it's in the not  
yet commented section. Now take care of the culprit section and  
divide it. And so on, until you've located the guilty line.

Theory and practice are the same, in theory, but, in practice, they  
are different.

Running emacs with -q option I can see the euro sign correctly.

I don't use anything like "display table".

For emacs22 I used these lines to show characters from utf:

;; (setq-default enable-multibyte-characters t)
;; (setq locale-coding-system 'utf-8)
;; (set-terminal-coding-system 'utf-8)
;; (set-keyboard-coding-system 'utf-8)
;; (set-selection-coding-system 'utf-8)
;; (prefer-coding-system 'utf-8)
;; (set-language-environment 'UTF-8)

but enabling or not makes no difference.

Also, in my .emacs I cant see anything else about coding system.

I will try bisecting....

In GNU Emacs 23 the first line is obsolete, and I think the last one  
as well. The last but one line sets a preference and can be useful.  
The other lines can help to solve problems, in case there are any.

The environment variable LC_CTYPE (or LC_ALL) sets how GNU Emacs  
handles the default encoding.

Maybe someone good with elisp, and for the good of us all,
could automate this bisection -- eg, not splitting defuns, etc.

AND even recursively, since I imagine that lots of .emacs-files
do a load-file on a 2nd-level ".emacs".

And maybe even then run emacs, with provided user-input!


This bisection-scheme -- I imagine we all use it -- sure involves
a lot of work (grunt-work)!



More on that "recursive" idea:  when the single-level bisection
homes in on the load-file as the problem, then a way (by hand,
I guess) to say "ok, bisection.{c,sh,...}, let's do it again,
but this time don't start bisecting until you get to that
load-library (or enter that file?)"?

(in the unfortunate situation that the "green shoots" they're
saying they see in this economy turn brown and die, and someone
here thus thereafter ends up with time on his/her hands, maybe then?)

Bisection is only useful by hand, otherwise it doesn't
matter and a sequential eval-test-loop is just fine.
Something like this.

(defun disect(&optional buffer pred)
  "Eval sexps in BUFFER until some condition is met.
If PRED is nil stop when an error occurs, otherwise stop when
PRED returns a non-nil value.

PRED must be side-effect free, e.g. not move point."
  (interactive
   (list (read-buffer "Disect: "
                      (current-buffer) t)
         (eval (read
                (read-string
                 "Predicate (default: check for errors): "
                 nil nil "nil")))))
  (let (result)
    (with-current-buffer (or buffer (current-buffer))
      (goto-char 1)
      (check-parens)
      (while (and (not (eobp))
                  (not result))
        (condition-case err
            (eval (read (current-buffer)))
          (error (unless pred
                   (setq result err))))
        (and pred
             (setq result
                   (funcall pred)))))
    (if (null result)
        (message "Nothing to report")
      (if (null pred)
          (message "Error here: %s" result)
        (message "Predicate fulfilled here")))))
