We do know the answer to this question, since XEmacs has had a separate character type since even before it was renamed to XEmacs. Basically: you make the room for it. Stefan PS: For what it's worth, I think it's a mostly irrelevant design choice (tho maybe it was different back in the days of 1MB machines): having a separate character type would occasionally be convenient, but then again it would also occasionally be less convenient. I don't think either choice is clearly superior in this context. [ In the context of a statically typed language, OTOH, I think you do want to have a separate character type. ]
