Comment(by mathieu@…):

 I confirm that Japanese text doesn't work when cairo and pango are
 compiled with +quartz. Ascii text does work though.

 By default, the "han" script (which is used for Japanese) is associated
 with the fontconfig backend instead of the atsui backend.

 If I force the "han" script to be associated with the atsui backend, I get

 PangoWarning: failed to choose a font, expect ugly output. engine-
 type='PangoRenderATSUI', script='han'

 although atsui does seem to support CJK according to
 http://developer.apple.com/legacy/mac/library/documentation/Carbon/Conceptual/ATSUI_Concepts/atsui_chap1/atsui_intro.html.

 I'm wondering if disabling the fontconfig backend in cairo/pango can make
 any difference. If that's so, adding a variant would be a nice thing to
 do. I'm willing to help with testing if needed.

 The main motivation for me in using the atsui backend is that I need to
 create an app bundle and it seems wiser to use native libraries whenever
 possible.
