Well, actually I've wished for a *lot* of non-ASCII characters at various
times.  More than you can fit in the 128 available slots.  But most of them
are so seldom used that I don't mind that they don't have reserved 8-bit
values.

There is no such key.  (Yes, Emacs *does* distinguish between C-m and C-j.
Besides, on most keyboards the big key labeled RETURN or ENTER generates C-m,
so if you preempt that for a pseudo-meta, you'd have to use an explicit C-j
(awkward to type) to get a newline.)  Not that it matters -- such editors
normally run in raw mode anyway, so they'd be bypassing the new feature.

If you want line-drawing characters, add a line-drawing font.  Don't try to
make the ASCII set do double duty.

Oh?  Underlining with backspace is not unheard of, but I think the escape
sequence \e[4m is more common, especially among "ANSI terminals".  Perhaps
you're confused by software that does this conversion for you (e.g. "more")?
And certainly very few terminals (hardcopy excepted) will display general
overstrikes like a cent sign.
