Actually, gb18030.2000-0 font just is the GBK font, and it has the ASCII in it.


ftang: this is strange. We know gbk font do not have ASCII , how can 
GB18030.2000-0 font have ascii if they are the same as GBK font ?

I believe I fix this by clear out the ASCII part of gb18030.2000-0 encoding. 
Please send me the font to [e-mail] so I can take a clear look at it. 

also, eyan- please send me your phone number by email. Thanks. I may need to 
talk to you over the phone. 

mark it fixed.

From file font.alias, we can see gb18030-0 use gbksong-medium fonts.

-sun-song-bold-r-normal--14-120-75-75-c-120-gb18030.2000-0     gbksong-medium12
-sun-song-bold-r-normal--16-140-75-75-c-140-gb18030.2000-0     gbksong-medium14
-sun-song-bold-r-normal--18-160-75-75-c-160-gb18030.2000-0     gbksong-medium16
-sun-song-bold-r-normal--22-200-75-75-c-200-gb18030.2000-0     gbksong-medium20
-sun-song-bold-r-normal--26-240-75-75-c-240-gb18030.2000-0     gbksong-medium24

gbksong-medium fonts can be got from Solaris system:
/usr/openwin/lib/locale/zh.GBK/X11/fonts/75dpi

gbksong-medium fonts contain ASCII font.

I will attached a snapshot image to show the ASCII font in gbksong-medium16 by
command "xfd -fn gbksong-medium16"

Verified in nightly build 2001052210:  Now the ASCII characters can be displayed OK.

But there is a GB18030 4 byte character "0x82358738" displayed as '?', others
are OK.

I will attach the images.

Ervin, can you mask this as VERIFIED, then can you file new one
for 0x82358738 problem?

Comment 12

[Ervin Yan]

In latest nightly: ASCII characters can display OK now. but:

Two 4-byte GB18030 characters displayed error:

Characters "0x82358738" display as '?', though it have font glyph. 
Characters "0x82358739" display as '?', though it have no font glyph.

I filed a new bug for the new problem.see bug 82666.
