You can find out it's \(mo by either looking at the Special Character
Names on the last page of CSTR 54, http://troff.org/54.pdf, or do what I
initial did on finding out LaTeX's \in was U+2208, ∈, examine
groff_char(7).

    $ man groff_char | sed -n '/^ *Output/{N;h}; /∈/{x;G;p;q}'
           Output  Input        PostScript      Unicode     Notes
                   name         name            decomposed
           ∈       \[mo]        element         u2208       +
    $

Cheers, Ralph.
