pango doesn't render non-Latin characters with cairo-quartz-font

[Ryan Schmidt-43]

Hello. I maintain cairo and pango in MacPorts, and I have a report  
from a user that when cairo-quartz-font is in use, pango doesn't  
render non-Latin characters (Chinese, Japanese, Korean, Thai,  
Tibetan). When cairo-quartz-font is turned off (i.e. when cairo-
quartz-font.pc is deleted and pango is rebuilt), these characters  
show up.

The reporter was using Mac OS X 10.5.x (Leopard) with cairo 1.6.4 and  
pango 1.20.3. I can confirm the issue with Mac OS X 10.4.11 (Tiger)  
on Intel with cairo 1.6.4 and pango 1.20.5.

Here is the detailed bug report that was filed with MacPorts:

http://trac.macports.org/ticket/15626

I don't know if this is a cairo bug or a pango bug. I thought I'd  
start by asking the pango list. Please let me know if you think I  
should ask the cairo list instead. Thanks.

I posed this question on July 3 and nobody responded. I also asked  
the cairo list on July 6 and nobody answered there either. Can anyone  
give me any guidance about how to deal with this issue?

Hi,

I'm interested in this issue. Until 2008-07-28, I don't
have sufficient time to reproduce the bug. If nobody
works for the bug until the day, I will try to analyze
the bug.

Regards,
mpsuzuki

If no one replied, chances are no one can give you any guidance about
how to deal with this issue.  At some point someone needs to dig into
the code, and that someone is not easy to find because of the
platform-specific nature of your issue.

I'm also surprised how that neither your report nor the "detailed bug
report" even mention what kind of "issues" it's showing.  No
screenshots.
