[copied text from bug]

ggv can read ps files in Chinese 
and acroread can read pdf files after installing an extra language package. 
When I use evince, it gives the error
"Error (59677): No font in show/space
Error: Unknown font tag 'TT2'
Error: Unknown font tag 'TT2'
Error: Unknown font tag 'TT2'
Error: Unknown font tag 'TT2'
Error: Unknown font tag 'TT2'
Error: Unknown font tag 'TT2'
Error: Unknown character collection 'Adobe-GB1'
Error: Unknown font tag 'TT2'
Error (62614): No font in show/space
Error: Unknown font tag 'TT2'

I also try evince, ggv and acroread with other  ps/pdf files, and find
for some files, it can display clearly.

My platform is FC3, gnome 2.10 beta 1

Description of problem:
evince cannot display most of my pdf files correct. The files are loaded ok but
the chinese characters turn out to be random meaningless symbols. Running in
terminal, I can see a lot of error output such as
Error: Unknown character collection 'Adobe-GB1'
Error: Unknown character collection 'Adobe-GB1'
Error: Unknown font tag 'F5'
Error: Unknown font tag 'F5'
Error: Unknown font tag 'F5'
Error: Unknown font tag 'F8'
Error: Unknown font tag 'F3'
Error (205398): No font in show/space
Error: Unknown font tag 'F8'
Error (205407): No font in show/space
and my system turned very slow when loading these files. These files are
produced by Acrobat Distiller 5.0 (Windows) and/or CTeX suite (Windows)

It can render some pdf files very well, which are produced using pdflatex in
tetex-latex-2.0.2 or dvipdfmx(20031207), the source file is in UTF-8. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. open a terminal
2. run evince
3. load a file that contains chinese characters

Actual Results:  If the pdf file is created using adobe distiller under windows,
then there would be alot of Error output, no chinese characters can be seen, but
a lot of strange symbols. Since most of my pdf files are produced that way
(adobe distillers + windows) and the source files(ppt, doc, etc.) are lost(bad
luck!), I cannot reproduce them under OOo. 
Most of the times, acroread displays them well.

Expected Results:  nothing should happen in the terminal, and the page displays
correctly, like acroread (with CHSKIT, language pack of acroread installed) does.

Additional info:

My default locale is zh_CN.UTF-8
when I switch to zh_CN.GB2312, the problem remains the same, so does the output
on terminal.

please try the patch I sent poppler mailing-list.

This patch maybe fixes your problem. and you need xpdf-chinese or something to
view correct chinese characters.

Comment 4 Pablo Rodríguez 2005-08-27 08:57:35 UTC
I don't know whether this bug is somehow related to the correct displaying of
CID encoded fonts using poppler-cairo. (Maybe I've drawn the wrong conclusions
from the fact that this document seem to use CID encoded fonts.)

Would it be possible to create a new patch so that poppler correctly renders CID
encoded fonts? (https://bugs.freedesktop.org/show_bug.cgi?id=4223)
Comment 5 Pablo Rodríguez 2005-09-10 12:02:32 UTC
CID font detection seems to be fixed in release 0.4.2.

Maybe this bug should be closed.
Comment 6 Hiroyuki Ikezoe 2005-11-01 16:01:54 UTC
This bug is not fixed yet.
It is not concerned with BUG #4223.
Comment 7 Funda Wang 2006-02-02 01:58:37 UTC
Hiroyuki, does your patch work on poppler CVS HEAD/0.5.x?
Comment 8 Kristian Høgsberg 2006-09-18 21:42:47 UTC
This should be fixed in CVS, provided the new poppler-data package is installed.
Comment 9 Kristian Høgsberg 2006-09-20 17:21:50 UTC
Closing bug.
