 quartz-font backend in cairo 1.6.4 might have a bug.
 It does not render non-latin characters properly.

 I guess there might be a flaw in its default font selection mechanism or
 something.

 Ryan, would you please take a look?  This is very serious problem since it
 affects all of gtk2 applications. Thanks.

 '''How to reproduce:'''

 1) Install cairo and pango from scratch.

 {{{
 $ sudo port install cairo pango

 $ port installed
 The following ports are currently installed:
   cairo @1.6.4_1+macosx (active)
   expat @2.0.1_0 (active)
   fontconfig @2.6.0_0+macosx (active)
   freetype @2.3.6_0 (active)
   gettext @0.17_3 (active)
   glib2 @2.16.3_0+darwin_9 (active)
   gperf @3.0.3_0 (active)
   libiconv @1.12_0 (active)
   libpixman @0.10.0_0 (active)
   libpng @1.2.29_0 (active)
   ncurses @5.6_0 (active)
   ncursesw @5.6_1 (active)
   pango @1.20.3_0 (active)
   pkgconfig @0.23_0 (active)
   render @0.9_1 (active)
   Xft2 @2.1.12_0 (active)
   xorg-util-macros @1.1.5_0 (active)
   xorg-xproto @7.0.11_1 (active)
   xrender @0.9.0_2 (active)
   zlib @1.2.3_1 (active)
 }}}

    After installing pango, run the below command
    to check whether these ports can render unicode text or not.

 {{{
 $ pango-view --backend=cairo ~/Desktop/utf8.txt

  (Result: picture1.png [NG])
 }}}

 2) Next, simply remove '${prefix}/lib/pkgconfig/cairo-quartz-font.pc'

 {{{
 $ sudo rm /opt/local/lib/pkgconfig/cairo-quartz-font.pc
 }}}

    and then rebuild pango. Due to this operation, pango will be built
    without cairo-quartz-font support.

 {{{
 $ sudo port uninstall -f pango
 $ sudo port install pango
 }}}

    After installing pango, please run pango-view again.

 {{{
 $ pango-view --backend=cairo ~/Desktop/utf8.txt

  (Result: picture2.png [OK])
 }}}

    That's it.
