Has anyone had any success with mark filter sets?
According bug #238 there is a problem with hb-open-type-private.hh where the to_int() function is programmed wrongly (need to multiply sizeof() by 8 when shifting). This would mean that no mark filter set lookups will ever succeed.
Has anyone managed to get harfbuzz to execute a lookup with a mark filter set in it?
Oh and you can't work around it by setting the gdef version to 0x40010002 because harfbuzz carefully sanitizes that away. So there's no workaround.
Back to MarkAttachment I suppose.
