Just a suggestion, it would be great if it were easier to do proper dash typography. I find TeX's -/--/--- convention for hyphen/en-dash/em-dash to be fairly intuitive.

Right now, if you do — in the text, it makes things much less readable and is confusing for newbies. The need for these glyphs is so common that wiki support seems worthwhile.

Actually, what is the need for these glyphs? :-)

I've been resisting for some time the strange obsession people have with typing — when a simple "-" character will do. When used as a dash, it's easily distinguised from a hyphen by the fact that it has spaces on either side of it.
