> Yes, as Behdad says we need to switch to the complex text path when appropriate. Behdad probably has more information about when the right time to do that is.

On Chrome Linux and Android we already switched to harfbuzz-ng. So, first step is to figure out who still uses harfbuzz.old and switch them over.

After that, it's just a matter of developing the heuristics. I personally think that we should get rid of the fastpath and always do complex text processing (requires adding new caches). But that's far from where we are right now.
