Unicode (and so HTML) also has

  U+2008  &#8208;   HYPHEN
  U+2212  &#8722;   MINUS SIGN

HYPHEN is not much used since in most fonts it's identical to ASCII ‘-’. MINUS SIGN is meant to be visually congruent with +×÷=, etc (same stroke width and appropriate alignment).

Personally I have - – — ‐ ‑ − on my usual keyboard layout.

Correction: hyphen is U+2010, not U+2008 (which is punctuation space).

Thanks. Too late for me to edit.

Hyphen is also a Western name separator, as in Jean-Luc Picard. Using a hyphen where a dash belongs, because of its ease of use on a typical U.S. layout keyboard, is a common mistake. A lot of people type two hyphens to make a dash, as well, partially because of ASCII, and it was nice to update my phone and Mac recently and see that Apple is now automatically fixing that by default without making me hold down the hyphen—disrupting my typing flow.

You could add the translation before, but it’s cool to introduce a lot of folks who don’t know that to a proper dash.
