This effort is not needed for GNU Emacs 23 (CVS unicode-2 branch).  
The CDAC fonts might be useful.

Right, but CDAC fonts are hard to get, they can be found here:

Some Font & Face Questions (unicode--2)

[Florian Beck]

I am stumped here. Bug? Read Another F' Manual? Compilcated? I don't
know anymore.

1. Recently I tried to display as much of HELLO as possible. So i looked
up the character ranges at unicode.org, searched for the recommended
fonts and set »set-fontset-font«.

This works quite well for

; Hebrew שלום
(set-fontset-font
 "fontset-default"
 '(1424 . 1535)   
 "-unknown-Code2000-medium-r-normal--16-*-*-*-*-*-unicode-bmp")

but not for

; Devanagari नमस्ते, नमस्का, 
(set-fontset-font
 "fontset-default"
 '(2304 . 2431)   
 "-unknown-Code2000-medium-r-normal--16-*-*-*-*-*-unicode-bmp")

though I am pretty sure the font can display devanagari characters. I a
bit at a loss here. Am I doing something wrong or are my fonts at fault
after all?

2. How do I find out about the possible fonts-specs? 

I build the above more or less by trial and error and examining my font
cache. The funny thing is, »xlsfonts« or »xfontsel« do not show the
fonts in which I am interested (eg Code2000, SimSun, Arial Unicode).

3. I can set frame specific fonts. This works ok. Can I show different
fonts in *windows*? If not, as I fear, can I at least have different
font sizes in different windows, e.g. small fonts in *Help* windows?

You did not mention whether you use in the experimental Unicode Emacs  
23 its font backend or not. Without it you need to edit X11's font  
path. This can be done for example in ~/.xinitrc, the script that  
launches the X clients and the window server:

	xset fp+ /usr/X11R6/lib/X11/fonts/cyrillic/,/sw/lib/X11/fonts/ 
applettf/,/sw/lib/X11/font        s/libwmf/,/sw/lib/X11/fonts/msttf/
	xset fp rehash

Before this actually can work you need to create the (fonts.alias,)  
fonts.dir and fonts.scale directory files for X11 with mkfontdir or  
such in each component of font path.


If you have enabled the font backend then fontconfig is managing  
Unicode Emacs' font use. This system relies on fonts.conf file, for  
example:

	/etc/fonts/fonts.conf
	/etc/fonts/local.conf
	/usr/local/etc/fonts/fonts.conf
	~/.fonts.conf

Then think of a longer break (lunch for example) and invoke as root  
and in your own account fc-cache – after half an hour or later you'll  
have the .fonts.cache-* files ...

I also have a ~/.fontconfig directory (almost 800 cache files, almost  
7 MB) of which I don't know where it comes from and what it's good  
for ...

No, not yet. All windows in one frame have to share the same font or  
fontset. But you can configure particular font faces to come from a  
particular font, be in a particular size or of a particular colour,  
shape ...

I'm using the new font backend.

I know this. My problem is that fonts I install do not show up in
xlsfonts or xfontsel, so figuring out the right foundry and family for
the font spect requires digging through several font.cache files. Maybe
my fontconfig is messed up? However, the fonts *are* installed: they
show up in gucharmap and in emacs

(set-fontset-font
 "fontset-default"
 'han
"-*-SimSun-medium-r-normal--18-*-*-*-*-*-unicode-bmp") 

works just fine.

But that is getting a little off topic here.

Nice, but not real practical for my purposes.

Thanks for your help.

I think you need to understand that xlsfonts and xfontsel rely on  
font path in X11 and do not use libfontconfig.

> Maybe my fontconfig is messed up?

Have you ever used the fontconfig utilities, for example fc-list?
