There are actually four different "dashes" in La/TeX. The hyphen (-), en-dash (--) which is used for numeric rangen like 1--2, the em-dash (---) for punctuation, and the minus sign ($-$). Knuth talks about them in the TeXbook which is good fun.
I think you can do all of those in plain text as well. There are Unicode characters for those dashes and probably more
Not in ASCII. My definition of plain text is roughly "the characters I have on my keyboard". Unicode is like a superset of all possible plain texts. Useful, but I really don't like my own files containing characters I can't (easily) type. If I regularly typed in another language I would acquire a keyboard for that language. I'm not even convinced typographical symbols like various dash types even belong in Unicode at all to be honest. It seems like you have to draw a very arbitrary line somewhere.
Drawing the line at "OK-ish for American English" is far too restrictive.
You can't write CO₂ or m², use a fraction like ½, claim © or mention a price in Euros or Pounds Sterling.
You can't even write major American place names (San José, Oʻahu).
