In the fonts I use, I've never noticed a difference between hyphen/dash/endash/minus. But (as alluded to in the intro of the submitted message) some fonts will render it differently. I would not be surprised if various screen-reading software handles them differently. So for some people, rewriting all of them into '-' would be information-discarding. (However, I'd not be surprised if there are more "incorrect" hyphen/dash/minus issues in many code bases than "correct" ones...)
