Indeed, it turns out that Indic text extraction had improved
dramatically since I has last tried it out, and using PDF/A made no
difference to lurking bugs.  (In case it be relevant, I'm using
HarfBuzz 1.2.7 as the system HarfBuzz library, which is the latest I
can get on my Ubuntu 16.04.3 machine using the Debian build system on
the Ubuntu distribution system.  It's probably time to risk an upgrade.)
