It's not incorrect, just making accommodations for the character
encoding.

FWIW, the Info file currently outputs with

     ‘−’ is a minus sign generated with ‘@minus{}’,

The − there is not an ASCII character.  Note also the directional
quote marks.

It's possible you have an old version of the manual, or that you
are running Info in a non-UTF-8 locale where fallback characters are
used.
