But they don't because you can't predict for many instances what "default"
"turning ligation on" could be. There _are_ no default ligatures for many
scripts, times, documents, etc. And I know that the designer can add in a
zillion levels of defaultness, but this is a clumsy kludge that burdens
designer and user alike.

Merle Tenney showed me how the AAT mechanisms work in a font workshop in
London last year. I was impressed. And I have been thinking about it all
this time. And impressive as it is, it doesn't satisfy my needs.

Portability, John. Also it is not _fair_ that Brahmic scripts have plain
text ligation and European scripts do not.

I am working on that paper....
