Bug 157630

Created attachment 72602 [details]
kwrite-test.txt

Test file to help reproducing the bug.

Procedure how to reproduce the bug:

Install the Novell-ricoh-fonts package
(/dist/full/full-i386/suse/noarch/Novell-ricoh-fonts.rpm).

Then:

export LC_ALL=ja_JP.UTF-8
kwrite Documents/kwrite-test.txt &

In the setup of kwrite, choose HGGothicB as the font to use
both for display on screen and for printing:

mfabian@magellan:~$ grep -i gothic .kde/share/config/*
.kde/share/config/kateschemarc:Font=HGGothicB,10,-1,5,50,0,0,0,0,0
.kde/share/config/kateschemarc:Font=HGGothicB,10,-1,5,50,0,0,0,0,0
mfabian@magellan:~$

Now print the buffer to a .ps file.

Try to show the .ps file with "gs":

    mfabian@magellan:~$ gs print.ps

    mfabian@magellan:~$

You see that HGGothicB has not been embedded because
gs is still trying to load external fonts. First it tries
to load Hggothicb-H but fails as such a font doesn't exist.
The correct name would be one of 

    HGGothicB-UniJIS-UTF8-H
    HGGothicB-EUC-H
    HGGothicB-H

(depending on the encoding). PostScript font names are case sensitive!

Then gs falls back to the standard Japanese PostScript font name
"Ryumin-Light", which works because the scripts in ghostscript-cjk
setup our Ghostscript so that "Ryumin-Light" always works if Japanese
fonts is installed ("Ryumin-Light" is made an alias for the "best"
installed Japanese Mincho style font).

This is of course not perfect because the style of font in the printout
is very different from the style of the font on the screen.

Further evidence that HGGothicB was not embedded:

mfabian@magellan:~$ grep %%BeginFont print.ps
%%BeginFont: Arial
%%BeginFont: ArialMT
mfabian@magellan:~$

Now setup kwrite to use any Japanese .ttf font instead of a .ttc font,
for example "Sazanami Gothic":

mfabian@magellan:~$ grep -i gothic .kde/share/config/*
.kde/share/config/kateschemarc:Font=Sazanami Gothic,10,-1,5,50,0,0,0,0,0
.kde/share/config/kateschemarc:Font=Sazanami Gothic,10,-1,5,50,0,0,0,0,0
mfabian@magellan:~$

mfabian@magellan:~$ fc-list "HGGothicB" file | grep truetype
/usr/X11R6/lib/X11/fonts/truetype/hgjgbbmp.ttc:
mfabian@magellan:~$ fc-list "Sazanami Gothic" file | grep truetype
/usr/X11R6/lib/X11/fonts/truetype/sazanami-gothic.ttf:
mfabian@magellan:~$

Print the same kwrite-test.txt from kwrite again.
View the result with "gs":

    mfabian@magellan:~$ gs print.ps

gs doesn't load *any* fonts, i.e. *all* fonts are already embedded
in the .ps file. This can also be seen with:

    mfabian@magellan:~$ grep %%BeginFont print.ps
    %%BeginFont: Sazanami Gothic Regular
    %%BeginFont: Sazanami-Gothic-Regular
    %%BeginFont: Arial
    %%BeginFont: ArialMT
    mfabian@magellan:~$

Mike Fabian> PostScript font names are case sensitive!

If qt3 used HGGothicB instead of Hggothicb, gs could at least find
the correct font. After editing the .ps output:

    mfabian@magellan:~$ diff print.ps.old print.ps
    8c8
    < %%DocumentFonts: ArialMT Hggothicb-H
    ---
    > %%DocumentFonts: ArialMT HGGothicB-H
    105,107c105,107
    < % Asian postscript font requested. Using Hggothicb-H
    < /Hggothicb-HList [
    < [ /Hggothicb-H 1.0 0.0 ]
    ---
    > % Asian postscript font requested. Using HGGothicB-H
    > /HGGothicB-HList [
    > [ /HGGothicB-H 1.0 0.0 ]
    808c808
    < /F2 false Hggothicb-HList MF
    ---
    > /F2 false HGGothicB-HList MF
    866c866
    < %%DocumentFonts: ArialMT Hggothicb-H
    ---
    > %%DocumentFonts: ArialMT HGGothicB-H
    mfabian@magellan:~$

gs loads the correct font instead of falling back to "Ryumin-Light":

    mfabian@magellan:~$ gs print.ps

Of course embedding the font is better, but probably the problem with
the wrong case in PostScript font names should be fixed as well.

No reaction from the KDE team on this. Is the case sensitive thing
something we still want/can fix at this time?
If not I would appreciate a suggestion where to move this bug,
e.g. 10.2, SP1 or CODE11.

The problem is unchanged in SLES10 build 1356 (as expected).

The problem still exists in openSUSE 10.2 and STABLE.

I have just tested this with Qt4 in STABLE (libqt4-4.2.2-23) using the
/usr/lib64/qt4/demos/textedit/textedit from the libqt4-devel-doc
package as the test case.

It works! Apparently all .ttc fonts can be embedded.

I don't think anybody has time to fix this in Qt3.  As it works in Qt4
already, it will work in KDE as well as soon as we have a Qt4 based
KDE. It is probably better to concentrate to have a Qt4 based KDE as
soon as possible instead of fixing bugs in Qt3.

Therefore I'll close this as WONTFIX.

By the way, it is the same with embedding of .otf fonts:

it works with qt4 but doesn't work with qt4.
