Exactly the same I told the old toaster: they both understand ASCII.

Emacs is capable of anything, provided you put enough effort into telling
it.  Assuming you're running on a pure ASCII display, or one running an
ISO-8859 character set (as I do), how much effort must you put into
telling Emacs (and standalone Info) that you really, really don't want
random Unicode bytes cluttering up your screen?

Not at all.  Quite a lot of people want Unicode, but quite a lot don't.
We shouldn't force it upon them.

Who's volunteering to do this?

Possibly.  But I have just the _tiniest_ suspicion that this is the thin
end of the wedge, the crack in the dyke, the floodgates wanting to burst
open.  How long before people start using Xah's fancy 3-byte quote marks,
with associated dangly bits hanging off them?
