I was wondering what's better. The document is clearer if we use unicode.

But maybe for humans it's easier if we have a limited character set and use context instead. Like this.

In plain text, - is a hyphen:

    twenty-five, -1

In math context - is a minus sign

    $ (-1)^3 + x^3 $

Where it will be ensured to be rendered as appropriate

It’s easier to type HYPHEN-MINUS‐the‐keyboard-key, but text should be displayed using the appropriate glyph, depending on its semantic meaning, which is never HYPHEN-MINUS‐the-glyph.

(This discussion is similar to the classic net discussion about TAB‐the‐ASCII‐character versus TAB‐the‐keyboard‐key, with some people having trouble conceptualizing the difference.)
