Most interesting. What about codex binding? When I see people reading
Chinese newspapers on the subway, the binding appears to be on the left
even though the columns of the text are RTL; at least, judging by what
appears to be the front page.
(ObJoke: A reporter for the New York Yiddish newspaper, the _Forvits_:
"Chief? Shpeisel here. I've got a story that'll rip this town wide open.
Hold the back page!")

Surely that's not enough: you'd need to implement the full implicit bidi
algorithm, giving Ogham a nonce bidi type of R. Either that, or run the
Ogham T2B instead of the normal direction.
