I can't imagine this working for Egyptian or Mayan, or indeed
Mongolian or Ogham.
Mongolian and Ogham, when mixed with Latin text, are traditionally
written LTR (sometimes Mongolian is RTL). It isn't normal or natural
to do otherwise.
Egyptian LTR or RTL is not problematic. But for columnar display, in
current applications, markup is used.
Mayan writes LTR or RTL in repeated columns of two, as I recall. I
strongly suspect markup is required for this behaviour.
