Should the fonts listed by xlsfonts be used by emacs?

[c.c]

Hi,

I am tring use the font simsun in my GNU Emacs 21.4.1. I think I have
setuped this font correctly, because I can see it in the xlsfonts's
output, like this

-misc-simsun-medium-r-normal--0-0-0-0-p-0-gb2312.1980-0
-misc-simsun-medium-r-normal--0-0-0-0-p-0-gbk-0
-misc-simsun-medium-r-normal--0-0-0-0-p-0-iso10646-1
-misc-simsun-medium-r-normal--0-0-0-0-p-0-iso8859-1
-misc-simsun-medium-r-normal--0-0-0-0-p-0-jisx0208.1983-0
-misc-simsun-medium-r-normal--0-0-0-0-p-0-jisx0208.1990-0
-misc-simsun-medium-r-normal--0-0-0-0-p-0-koi8-r

but when I try to use these fonts in my emacs like this

emacs -fn "-*-simsun-medium-r-*-*-12-*-*-*-p-*-gb2312.1980-*"

I always fail with message "X protocol error: BadName (named color or
font does not exist) on protocol request 77".

what's wrong ?

Thanks.

If you are using `"´ on the command line, then your shell is trying  
expand the asterisks. You should use `'´ instead. And, since all  
these simsun fonts are proportional, you can change p to *, and since  
since there is only one in gb2312.1980 you can change the final * to 0.

Another way to solve the problem is to invoke xfontsel and make it  
choose a particularly scaled font. The press select, and you can  
paste that font name into xterm or a file.

Hi, Peter,

Thanks for your reply.

But your method doesn't work for me, I tried the xfontsel and used the
most simple result '-mis-simsun-medium-*-*-*-*-*-*-*-*-*-*-*', the same
result.

And I am also puzzled why I can't find the entry for simsun font in the
the completion list when I type M-x set-default-font <TAB>. I think it
should be there if the xlsfonts can list it.

best regards,

I think, the -fn switch want a fontname or font_set_name, not things
like "-*-simsun-medium-r-*-*-12-*-*-*-p-*-gb2312.1980-*". The later is a
 XLFD fontset pattern.

IN emacs do:

C-h i d m emacs i fontset

and you will see the fontset-related manual.

What I can think of is, font-config is being used. It has it's own  
configuration file(s) (system and user). (fc-cache, fc-list,  
fontconfig(3))


I thought you would try to find in xfontsel a font name without any  
asterisks, i.e. with everything specified. And using the select  
button you would not be able to make a mistake (like above?) when  
passing this font name to GNU Emacs.

Hi, guys,

I found the answer, the manual says:

"
   If you specify a default ASCII font with the `Font' resource or the
`-fn' argument, Emacs generates a fontset from it automatically.  This
is the "startup fontset" and its name is `fontset-startup'.
"

I think the 'emacs -fn' wants a ASCII font name, but the name I gave
is a mbyte font name, so Emacs can't generate a fontset correctly.

Thanks you all.

Best regards.

That seems plausible, if you substitute "unibyte" for "ASCII" since
Emacs has no problem with e.g. the ISO 8859-* fonts specified via -fn
or a Font resource.

There was an -iso8859-1 version of the same font, try that (since it
is generating a fontset, you should still get the -gb2312.1980-0 font
you want for the Chinese characters).

On the other hand, it is proportional, which may also cause problems
for use as the default font.
