Using r36309, Arabic text got rendered with the specified font (thanks to fixing #16942), but when I use @font-face CSS property (downloadable fonts) only Latin part get rendered using the specified font, while Arabic is rendered using one of my system fonts.

Created attachment 23347 [details] testcase The web-font.html and installed-font.html should be rendered the same (of course you need to install the font for the later to work)

Confirmed. This is blocked by Pango: http://bugzilla.gnome.org/show_bug.cgi?id=347237 Downgrading bug to P3 because there's nothing we can do about it until Pango is fixed and the text is still legible. Please let us know when the fix gets into Pango so we can support this!

This no longer appears to be an issue. The @font-face font is used (with the FreeType backend). Unfortunately, since we do not have complex text support for @font-face fonts yet, the render is totally incorrect. The attached test cases are very nice and I'd like to preserve them, so I'll update the title of this issue to reflect the current state of things.

Is this covered by bug 92098?

Yeah, switching to HarfBuzzNG will fix this issue.
