- 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

- 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.
