chinese font setup problem

chinese font setup problem

[William Xu]

I try to setup chinese fonts display.  Start emacs23 with `-Q', all
chinese fonts are displayed hollow boxes:

,----[ C-u C-x = ]
|         character: 华 (21326, #o51516, #x534e)
| preferred charset: chinese-gbk (GBK Chinese simplified.)
|        code point: 0xBBAA
|            syntax: w 	which means: word
|          category: C:Chinese (Han) characters of 2-byte character sets
| 		   c:Chinese
| 		   |:While filling, we can break a line at this character.

Compared with emacs22, also with `-Q', chinese fonts are displayed
correctly, for example: 

,----
|   character: 华 (40362, #o116652, #x9daa, U+534E)
|     charset: chinese-gb2312 (GB2312 Chinese simplified: ISO-IR-58.)
|  code point: #x3B #x2A
|      syntax: w 	which means: word
|    category: C:Chinese (Han) characters of 2-byte character sets c:Chinese
| 	     |:While filling, we can break a line at this character.
| buffer code: #x91 #xBB #xAA
|   file code: #xE5 #x8D #x8E (encoded by coding system mule-utf-8)
|     display: by this font (glyph code)
|      -arphic-ar pl sungtil gb-medium-r-normal--18-180-72-72-c-179-gb2312.1980-0 (#x3B2A)
| 
| There are text properties here:
|   fontified            t
| 
| [back]

In emacs23, using `M-x set-default-font', I have tried various chinese
fonts, but it could never display chinese fonts correctly.  Any ideas?

What do you get with `xlsfonts | grep gbk'? Do you have any font with the
`gbk-0' encoding? If not, go to your chinese font directory and issue these
commands:

mkfontscale -a gbk-0
mkfontdir

Can't reproduce the bug. 
Did your emacs bootstraped with `--enable-font-backend'? 
What's your locale and language configuration?

Hmm...what is your build version?

No. configured only with `--prefix=$HOME'.

I build a version without `enable-font-backend', 
but still can't reproduce the bug.

Do you have any truetype chinese font installed beside 
the wenquanyi bitmap font?

It looks like there is a difference on which x-toolkit is configed to
use.  Mine is none. Not sure whether this matters.

Seems not.  But there are some other chinese fonts available: 

,----
| -default-song-medium-r-normal--8-80-72-72-m-80-iso10646-1
| -default-song-medium-r-normal--8-80-72-72-m-80-iso8859-1
| -isas-fangsong ti-medium-r-normal--0-0-72-72-c-0-gb2312.1980-0
| -isas-fangsong ti-medium-r-normal--16-160-72-72-c-160-gb2312.1980-0
| -isas-song ti-medium-r-normal--0-0-72-72-c-0-gb2312.1980-0
| -isas-song ti-medium-r-normal--16-160-72-72-c-160-gb2312.1980-0
| -isas-song ti-medium-r-normal--24-240-72-72-c-240-gb2312.1980-0

Do you think this is a font missing problem? I don't understand, since
emacs22 on the same system can display chinese texts correctly.

I build a version without font-backend, and installed the xfonts-wqy package of
debian sid, and use the following configuration:

(set-fontset-font "fontset-default" 'gb18030
"-wenquanyi-wenquanyi bitmap 
song-medium-r-normal--16-160-75-75-p-80-iso10646-1")

Emacs display chinese characters with wenquanyi font with no problem.

This problem is quite weird.

Ah, set-fontset-font also works here.  `M-x set-default-font' won't.
There seems to be some differences between these two then.
