It's even more complicated as there's an additional near-identical character in Unicode. Copied from Wikipedia:

    - is a hyphen-minus (ASCII 2D, Unicode 002D), normally used as a hyphen, or in math expressions as a minus sign
    – is an en dash (Unicode 2013). 
    — is an em dash (Unicode 2014). 
    − is a minus (Unicode 2212).
