What?  The weird parsing rules are part of the ASCII one; it's what the
Unicode is trying to *avoid*. We're just about out of ASCII, weird parsing
is going to be required at some point.

I also wish to note that I have never been a member of the "anything beyond
plain ASCII is fundamental evil" set; if we're going to think that way,
just go back to BAUDOT and punched cards.
