Tell us a little more about how you are trying.  It works here for some
of my tests.

    $ echo '\[-+]' | nroff | grep .
    ∓
    $ echo '\[-+]' | nroff -Tascii | grep .
    -+
    $ echo '\[-+]' | nroff -Tiso-8859-1 | grep .
    ∓
    $

I'm guessing it's to do with the type of output you're producing.

Cheers, Ralph.
