Description Zhe Su 2005-08-26 07:40:50 UTC
I tried to install a SUSE 10.0 beta3 with Simplified Chinese language. Packages
of Traditional Chinese, Japanese and Korean were selected as well. Then I found
that there were some Simplified Chinese characters couldn't be displayed
correctly during the second stage installation. See attached screenshots.

5 CD i386 version was used for installation.

I found that:

1. Bitmap font newunifont.pcf.gz was used during the first stage. It's ok for
both SC and TC. However there is a bug #66498 we should fix.

2. ttf-founder-traditional-0.20040419-6.noarch.rpm is in the first CD, but
ttf-founder-simplified-0.20040419-6.noarch.rpm is in the second CD. So ttf fonts
for TC were installed into the system before the second stage. But ttf fonts for
SC were not installed yet.

3. During the second stage installation, yast will load both newunifont.pcf.gz
and FZMingTiB.ttf (a TC ttf fonts provided by ttf-founder-traditional package).

I think that's the reason why some characters were missing.

I suggest two ways to solve this issue:
1) put both ttf-founder-traditional and ttf-founder-simplified packages into CD1.
2) remove both of them from CD1 and put them into other CDs. So we only use
newunifont.pcf.gz for every installation stages.

See the characters in the red circle. All of them became black boxes.

There is another font issue during the second stage installation. The size of
Latin characters in the dialog area are too small. See the following attachment.

The font size of release notes are very small.

Zhe Su> 1) put both ttf-founder-traditional and ttf-founder-simplified
Zhe Su> packages into CD1.

This would fix the problem with the sizes reported in comment #2 as
well.  The problem is not that the Latin characters are to small, the
problem occurs because the Chinese characters are too big. They are
from a 16x16 bitmap font and therefore cannot scale down.

Comment 5 Mike Fabian 2005-08-26 10:52:12 UTC
Zhe Su> 2) remove both of them from CD1 and put them into other
Zhe Su> CDs.

This would probably fix the problem of the missing glyphs because then
FZMingTi cannot be used anymore in the second stage of the
installation and the Gnu Unifont is complete enough both for
simplified and traditonal Chinese.

Zhe Su> So we only use newunifont.pcf.gz for every installation
Zhe Su> stages.

Only for the second stage of the installation when done from CDs.

When an installation is done from the (9GB) DVD, the TrueType fonts
are already installed before the second stage, therefore the TrueType
fonts can be used for all stages of the installation.  In the first
stage of the installation they can be used when Chinese is selected in
Linuxrc.

Comment 6 Mike Fabian 2005-08-26 10:54:17 UTC
As the TrueType fonts need a lot of space, putting all TrueType fonts
needed for CJK on CD1 might not be possible though.  It would be the
best solution, but it might not be possible. We must leave this for
the CD-creation team to decide.

I think installation from CD should be seen as a fallback only when no
DVD drive is available.

Comment 7 Arvin Schnell 2005-08-26 10:59:08 UTC
Do we have space on CD1?
Comment 8 Zhe Su 2005-08-26 11:24:11 UTC
DVD recorder is not as popular as CD recorder, at least in China. And 5CD
version is smaller than DVD version, so downloading is faster.
Therefore, CD version is still very popular in China.

Steffen just told me (to my surprise) that there is no second stage installation anymore, i.e. there is no reboot any more after CD1. I must get a Beta3 CD-set and see for myself.  If this is true, it would not matter anymore whether the fonts are on CD1 or not.  Of course it still matters whether they are in the instsys though (also on CD1).

This bug is very similar to bug #66498, I'll close it as duplicate,
it's enough to discuss this in one place.
