Does anyone know why epub reading software running on a PC has more capability than what runs on an ereader?
I seem to recall that ADE on a desktop can display almost anything (arabic, vertical chinese characters), stuff that it can never display properly or at all on a reader device.
How much can ADE (and for that matter, other epub readers), running on a desktop/full computer system, call on the OS's drivers and rendering engines to do things that it itself can not do?
I mean, does it have a fallback, say, on windows, to use windows' rendering engine to display, say, arabic?
