It should be possible to build the patched u_shapeArabic into WebKit. That
would also lock in (or allow fixing of) the Lam-Aleph quirk mentioned in
FontMac.mm:298.

I'm concerned about testing, though. I don't have a source for test data and if
I make a test I'm not sure I'll know what to expect. Automatic testing poses
another problem, since Tiger doesn't ship with any fonts that trigger the ICU
code path. It is now possible to bundle extra fonts with DumpRenderTree, but I
don't know if there's a suitable font that's compatible with WebKit's licensing
requirements. In the long term, I think it would be nice to create a font for
testing this and a few other code paths in WebKit that are only selected for
fonts with pathologies that don't exist in standard fonts (e.g. non-zero-width
zero-width-space, non-mirrored mirrored characters).
