Emacs fonts and unicode

Emacs fonts and unicode

[Paulo J. Matos]

Hello all,

I grabbed emacs-cvs from gentoo package system portage. Current
version is then:
GNU Emacs 23.0.60.1 (x86_64-pc-linux-gnu, GTK+ Version 2.12.9)

I am trying to view a couple unicode characters and have smooth characters.
I have tried with Shift-leftmousebutton several configurations but all
have something wrong. They don't look nice or they don't display the
unicode characters. I want both.
I have took a couple of screenshots:
Misc Fixed: http://users.ecs.soton.ac.uk/pocm06r/emacs-misc-fixed.png
Fontset startup 10dotmedium:
http://users.ecs.soton.ac.uk/pocm06r/emacs-fontset-startup-10dotmedium.png
Fontset standard 16dotmedium:
http://users.ecs.soton.ac.uk/pocm06r/emacs-fontset-standard16dotmedium.png

The first is ok but doesn't display unicode (see the boxes)?
The second is terrible but displays unicode.
The third is perfect (except letters are probably too big) but no unicode.

How can I have the best of both worlds?

Cheers,

Try to extend the fontset(s) you use with something like this:

   (set-fontset-font "fontset-default" (cons (decode-char 'ucs #x2000)
   					 (decode-char 'ucs #x206f)) '("dejavu sans" .  
"iso10646-1"))	; General Punctuation

Before you do so (for every fontset and each of its sizes) you should  
check which fonts have the characters you see as boxes. You are not  
restricted to iso10646-1 encoded fonts, you could also use CJK fonts,  
they just need to provide these glyphs. To determine their Unicode  
value, position the mouse cursor on each of them and type:

	C-u C-x =

You don't need to specify a whole Unicode character block, you can  
use an arbitrary range or even just one code point you want to specify.

Nothing seems to change by adding this .emacs.
Am I missing something? Font is of good size but still aliased and
without unicode.

Are you using the "fontset-default" fontset? If not, then augment the  
one you are using.

The HELLO buffer (C-h H) shows the changes for me – otherwise I would  
not have written a theoretical contribution. Another, more complete  
test, is the utf8.txt in Kermit.

How do I know if I am using the fontset-default? Moreover, in the
fontset menu with shift left mouse button I don't get any default
option. Instead I get standard 16dotmedium and startup 12dotmedium.

Nope... :( HELLO buffer doesn't change.

By questioning GNU Emacs: M-x describe-fontset RET RET

(I think it also has the name *-fontset-startup.)

So change these! They're some debian gifts.

Thank you for all the suggestions. It's great now. I found the
problem. I had a .emacs.elc which was being used but the new .emacs
was not being recompiled so everything I added to the files was not
changing anything.

Cheers,

I'm happy (so far) using:
(add-to-list 'default-frame-alist '(font . "DejaVu Sans Mono-9"))

Haven't played much with unicode, though.

Should I notice any change? I added this to my .emacs but without any
noticeable change...

My configure has: --enable-font-backend --with-xft --with-freetype

I am using gentoo with emerge emacs-cvs so I think I am compiling with
--with-xft but not sure about the other two.
Are you also using emacs 23 from cvs?

In a second or third frame too? You might need to apply this for  
initial-frame-alist too and best remove the X resource that sets GNU  
Emacs' default font.
