ePub handles surrogate fonts that allow Chinese characters to be displayed from Extension Plane B? With one exception, that is not licensed for distribution, Extension Plane B support exclusively comes from the use of additional fonts. In other words, characters would have to be explicitly indicated to use one of two fonts, in order to display at all. Oh, and what about vertical writing?

Indian languages, as Arabic, have morphing/changing characters whose logic can be embedded right into the OTF font.

All of these things work?

I know the first is supported, but I'm not so sure about the second. Here is the relevant part of the spec:
