Emacs and fontsets

Emacs and fontsets

[Tassilo Horn]

Hi,

I use a two weeks old CVS Emacs. I want to get it display unicode chars
in a different font than "normal" ascii text. I've put these line in my
~/.Xdefaults:

,----
| Emacs*Font: fontset-normal 
| Emacs*Fontset-0:\
|  -xos4-terminus-medium-*-*-*-14-*-*-*-*-*-fontset-normal,\
| mule-unicode-2500-33ff: -gnu-unifont-*-*-*-*-16-*-*-*-*-*-iso10646-1,\
| mule-unicode-e000-ffff: -gnu-unifont-*-*-*-*-16-*-*-*-*-*-iso10646-1,\
| mule-unicode-0100-24ff: -gnu-unifont-*-*-*-*-16-*-*-*-*-*-iso10646-1
`----


When I start emacs now the font really is xos4-terminus-..., but unicode
chars aren't displayed (only squares). 

When I open a file with normal text and unicode chars, move the point
over a text part and do `C-u C-x =' I get:

,----
|   character: ( (050, 40, 0x28, U+0028)
|     charset: ascii (ASCII (ISO646 IRV))
|  code point: 40
|      syntax: () which means: open, matches )
|    category: a:ASCII   l:Latin  
| buffer code: 0x28
|   file code: 0x28 (encoded by coding system mule-utf-8-unix)
|     display: by this font (glyph code)
|      -xos4-Terminus-Medium-R-Normal--14-140-72-72-C-80-ISO8859-1 (0x28)
| 
| There is an overlay here:
|  From 14 to 15
|   semantic  ("setq" code nil nil #<overlay from 361 to 397 in .gnus.el>)
| 
| 
| 
| There are text properties here:
|   face    [nil]
|   fontified t
`----

When I move it over such an undisplayed unicode char and press `C-u C-x
=' I get:

,----
|   character: ? (01110040, 299040, 0x49020, U+2500)
|     charset: mule-unicode-2500-33ff (Unicode characters of the range
|     U+2500..U+33FF.)
|  code point: 32 32
|      syntax: w  which means: word
| buffer code: 0x9C 0xF2 0xA0 0xA0
|   file code: 0xE2 0x94 0x80 (encoded by coding system mule-utf-8-unix)
|     display: no font available
| 
| There is an overlay here:
|  From 14 to 15
|   semantic  ("if" code nil nil #<overlay from 6007 to 6600 in .gnus.el>)
| 
| 
| 
| There are text properties here:
|   face                 [font-lock-string-face]
|   fontified            t
`----

What's the mistake? What do I have to change, to get the unicode chars
displayed in -gnu-unifont-*-*-*-*-16-*-*-*-*-*-iso10646-1?

Regards and much thanks in advance,
Tassilo

   hmm...I think the '-gnu-unifont-' is not really font name. It's
   likely to indicate some fonts that contain unicode
   characters. You can install 'gnu-intlfonts' package:

   http://ftp.gnu.org/gnu/intlfonts/

   Install it according to README & INSTALL and modify your
   ~/.Xdefaults as follows:

   ---------------------------------------------------------------------------
   
   Emacs*Font: fontset-normal 
    Emacs*Fontset-0:\
    -xos4-terminus-medium-*-*-*-14-*-*-*-*-*-fontset-normal,\
    mule-unicode-0100-24ff:-misc-fixed-medium-r-normal--16-*-*-*-*-*-iso10646-1,\
    mule-unicode-e000-ffff:-misc-fixed-medium-r-normal--16-*-*-*-*-*-iso10646-1,\
    mule-unicode-2500-33ff:-misc-fixed-medium-r-normal--16-*-*-*-*-*-iso10646-1

    --------------------------------------------------------------------------

   Good luck!

I'm quite sure that -gnu-unifont-*-*-*-*-16-*-*-*-*-*-iso10646-1 is a
font name. If I put

Emacs*font: -gnu-unifont-*-*-*-*-16-*-*-*-*-*-iso10646-1 

in my ~/.Xdefaults and start Emacs and comment out the Fontset part
above all unicode chars are displayed correctly, but this font causes
some very strange behaviour (Some spaces are wider than
others.). Therefore I wanted to use it only when it'r really needed.

I cannot use the .Xdefault lines you gave me, because there are some
missing chars with it I need, e.g. the unicode thread arrows I use with
Gnus. (Look at my.gnus.org for "Gnus displaying threads using Unicode
chars and tree style Summary".)

But thanks a lot for your quick answer.

Maybe create-fontset-from-fontset-spec could be helpful to you.

Here is an part of my .emacs where i define a custom fontset for Mac OSX.
It seems sometimes buggy (with  french accentuated letters when displayed in
another frame than initial one letters are bigger -- if anyone can help)

(if window-system 
	(progn
	  (set-background-color "gray90")
	  
	  ;;X fonts specs format (désignation des fontes X)
	  ;;-FOUNDRY-FAMILY-WEIGHT-SLANT-WIDTH--PIXELS-POINTS-HRES-VRES-SPACING-AVEWIDTH-CHARSET 
	  
	  ;; Set frame size, color and fonts
	  (create-fontset-from-fontset-spec
	   "-*-monaco-*-*-*-*-9-*-*-*-*-*-fontset-monaco,
          ascii:-apple-monaco-*-*-*-*-9-*-*-*-*-*-*,
          latin-iso8859-1:-apple-monaco-*-*-*-*-9-*-*-*-*-*-mac-roman,

          latin-iso8859-15:-apple-monaco-*-*-*-*-9-*-*-*-*-*-mac-roman,
          utf-8:-apple-monaco-*-*-*-*-9-*-*-*-*-*-mac-roman,
          mule-unicode-0100-24ff:-apple-monaco-*-*-*-*-9-*-*-*-*-*-mac-roman,
        mule-unicode-2500-33ff:-etl-fixed-*-*-*-*-9-*-*-*-*-*-mac-roman")
	  ;;mule-unicode-2500-33ff:-etl-fixed-medium-r-normal--14-140-75-75-m-140-mac-roman")
	  ;;mule-unicode-2500-33ff:-apple-monaco-*-*-*-*-9-*-*-*-*-*-mac-roman")
	  ;;latin-iso8859-9:-apple-monaco-*-*-*-*-9-*-*-*-*-*-mac-roman,
	  (setq default-frame-alist '((width 		. 		120) 
								  (height 		. 		44) 
								  (top 		. 		440);pixels
								  (left 		. 		260);pixels
								  (font 		. 		"fontset-monaco");fontset-mac
								  ))
	  )
  )

Hi Sebastian,

Tang (zrr) wrote me an email with the solution. These lines work:

Emacs*Font: fontset-normal
Emacs*Fontset-0:-xos4-terminus-medium-*-*-*-14-*-*-*-*-*-fontset-normal,\
mule-unicode-2500-33ff:-gnu-unifont-*-*-*-*-16-*-*-*-*-*-iso10646-1,\
mule-unicode-e000-ffff:-gnu-unifont-*-*-*-*-16-*-*-*-*-*-iso10646-1,\
mule-unicode-0100-24ff:-gnu-unifont-*-*-*-*-16-*-*-*-*-*-iso10646-1
                       
The problem was that I had a space between mule-unicode-xxxx.xxxx: and
the font.

Tassilo
