Special characters on Emacs/Mac?

Special characters on Emacs/Mac?

[Ulrich Hobelmann]

I just can't stop it...

I guess the default encoding of Emacs is ISO-Latin-1, at least that's 
what I want to use anyway.

How can I input accented characters / German Umlauts, etc.?

Actually I think the problem is not the input, but the font: how do I 
change my
(set-face-font 'default "-apple-Bitstream Vera Sans 
Mono-regular-r-normal--13-140-75-75-m-120-mac-roman")
to use ISO-Latin-1 encoding instead of mac-roman?  The documentation 
didn't really help me there... (and my tries were worthless)

I don't know if the font makes a difference, but have you tried M-x
iso-accents-mode?

Here are most of them:

A " and a vowel produce ö.

A ` and a vowel produce à.

A 'and a vowel produce á.

A tilde gives you ñ, ç, ¡, ¿

A ^ and a vowel gives you ô.

The Carbon variant is Mac Roman. It accept the umlauts and other 8 bit 
characters from your keyboard.

You could try some of these:

	(setq process-connection-type t)
	(require 'site-fontsets-carbon)
	;(setq mac-command-key-is-meta nil)
	(set-language-environment               'German)
	(setq file-name-coding-system           'utf-8)
	(setq default-buffer-file-coding-system 'mac-roman-unix)
	(set-default-coding-systems             'mac-roman-unix)
	(set-keyboard-coding-system             'mac-roman)
	(prefer-coding-system                   'mac-roman-unix)
	(global-set-key [kp-delete]             'delete-char)
	  (set-default-coding-systems           'iso-latin-9-unix)
	  (set-keyboard-coding-system           'iso-latin-9)
	  (prefer-coding-system                 'iso-latin-9-unix)
	  (setq mac-transparency-alpha 80)
	  (setq initial-frame-alist '(
	        (mouse-color      . "midnightblue")
	        (foreground-color . "midnightblue")
	        (background-color . "antiquewhite1")
	        (font . "fontset-14pt_bitstream_courier")
	        (top . 10) (left . 650) (width . 89) (height . 60)))
	  (setq default-frame-alist '(
	        (background-color . "ghost white")
	        (foreground-color . "grey10")
	        (vertical-scroll-bars . left)
	        (font . "fontset-12pt_lucidasans_typewriter")
	        (cursor-color . "purple")
	        (cursor-type . box)
	        (top . 20) (left . 150) (width . 89) (height . 56)))

and look into the archves of the Mac OS X Emacs list, around last 
Christmas I published there a list of fontsets for the Carbon and X11 
environments, but the latter one is probably a bit incorrect:

I recommend you don't try that.  iso-accents-mode is an old package that was
designed before Emacs was extended to support all kinds of funny charsets.
It still mostly works but has a few misfeatures.

Nowadays you should use input-methods instead.  Try C-\ (or C-u C-\ to see
what are your options).

No, the font itself uses mac-roman encoding, so you'd have to change the
font-data itself.  Emacs happily uses fonts with mac-roman encodings, so
there's no reason to make such a change.

The problem is most likely elsewhere.  E.g. that your files are read as if
they were encoded in "mac-roman" whereas they're encoded in "latin-1" (or
vice-versa).  Check buffer-file-coding-system and
default-buffer-file-coding-system.

Re: Special characters on Emacs/Mac?

[Ulrich Hobelmann]

Thanks to all responses.

However, it still doesn't work.

When I load a file which is latin-1, and switch 
default-buffer-file-coding-system to 'iso-latin-1-unix, it displays the 
little "1" at the bottom of the buffer, but the font doesn't display the 
other characters (umlauts, ß), but only boxes.

It was a long and weary battle but I got some advice and solved the
problem with this:

(create-fontset-from-fontset-spec
                                
"-apple-monaco-medium-r-normal--12-*-*-*-*-*-fontset-monaco,
        ascii:-apple-monaco-medium-r-normal--12-120-75-75-m-120-mac-roman,
        mule-unicode-0100-24ff:-apple-lucida grande-medium-r-normal--0-0-75-75-m-0-mac-roman,
        mule-unicode-2500-33ff:-apple-bitstream vera sans mono bold-medium-r-normal--0-0-75-75-m-0-mac-roman,
        latin-iso8859-15:-apple-monaco-medium-r-normal--12-120-75-75-m-120-mac-roman,
        latin-iso8859-1:-apple-monaco-medium-r-normal--12-120-75-75-m-120-mac-roman"
)

(set-face-font
 'default "-apple-monaco-medium-r-normal--12-*-*-*-*-*-fontset-monaco")

for 9 points 

(create-fontset-from-fontset-spec
"-apple-monaco-medium-r-normal--9-*-*-*-*-*-fontset-monaco,
        ascii:-apple-monaco-medium-r-normal--9-90-75-75-m-90-mac-roman,
        mule-unicode-0100-24ff:-apple-lucida grande-medium-r-normal--0-0-75-75-m-0-mac-roman,
        mule-unicode-2500-33ff:-apple-bitstream vera sans mono bold-medium-r-normal--0-0-75-75-m-0-mac-roman,
        latin-iso8859-15:-apple-monaco-medium-r-normal--9-90-75-75-m-90-mac-roman,
        latin-iso8859-1:-apple-monaco-medium-r-normal--9-90-75-75-m-90-mac-roman")

Sadly I lost the references for the credits :(.

Hmmm...  I think thak  the use  of mac  roman is  in second  place for
deserving  a  rightful  spanking  (for  Apple  developers)  after  the
implementation of cp, mv and so on ... :)

You have to use fontsets -- or use an Emacs from CVS and report this 
bug!

Please remember that this is a development version, so you shouldn't try to
just work around problems.  Instead you should report them via M-x
report-emacs-bug so that they can be addressed.  Proving a workaround in the
bug report can be a useful addition, tho.

I.e. please report your problem via M-x report-emacs-bug, thank you.

Thanks!  That solves the display problem.

Emacs doesn't work with the Mac input method, though (alt-s doesn't do 
ß, but §).  I suspect the Alt key is mapped for something...

Well, I might check out the other input methods suggested in this thread.

What's wrong with cp, mv ...?
Aren't they just from FreeBSD?

Using the  Emacs Input Method  (I prefer this  since I use Emacs  in 3
differnt OS) solves the problem.  You can choose between german prefix
where ß  is the result  of the sequence  " and s (prefix  version work
somethin  like iso-accents-mode,  so wovels  with umlauts  are entered
with the sequence " (wovel)) and german postfix where you get the same
result by hitting  s and then z. In this mode  wovels with umlauts are
entered typing what I think is  the "no umlaut version" of the word (I
don't speak German -blame on me- so I'm not sure...).

The commands  do come  from BSD  or GNU. But  the filesystem  not, and
those smarties did not adapt the commands to the filesystem.

So  if  you cp  a  file  you cp  just  the  data  losing the  extended
attributes.  mv  should behave  likewise too.  There  are a  couple of
utilities that fix this in the development stuff. I never used them as
I use my iMac  as a Unix box and I don't care  of the other file forks
(btw does someone know a free  utility to repartition the disk to make
place to an healy Debian GNU/Linux ?).

Have you checked mac-command-key-is-meta too?

That variable is t.  So I guess alt should be free for other things, or 
does Emacs somehow interfere with the native input method?  Anyhow, I 
guess I could live with the latin-1-prefix or some other Emacs input method.

Thanks!

You shouldn't guess that much, but read a bit:

mac-command-key-is-meta's value is t

	Non-nil means that the command key is used as the Emacs meta key.
	Otherwise the option key is used.

In your situation the alt or the option key ⌥ is free create all the 
special glyphs of your Mac's keyboard. These can be meaningful too:

	(set-language-environment		'German)
	(setq file-name-coding-system	'utf-8)
	(setq default-buffer-file-coding-system 'mac-roman-unix)
	(set-default-coding-systems		'mac-roman-unix)
	(set-keyboard-coding-system		'mac-roman)
	(prefer-coding-system			'mac-roman-unix)

Mmh, looks like my personal fontset making attempt ;)

But it  is not satisfying enough as  it fails to display  some unicode chars
(e.g: box drawing U2500 et al) and it shows cyrillic ones instead.

A more constructive approach would be to fix the problem rather than work
around it:  i.e. try and help us get Emacs to correctly use the built
in fonts.

Indeed. But if i  am a developer and everyday Emacs user,  i have not enough
skills to  actively help correct internals  of Emacs apart  doing some tests
with cvs version and report bugs. :(
