I don't think they're in the Plan 9 source either.

    ni.c:
    349 Spnames spnames[] =
    350 {
    351         &c_hyphen,      "hy",
    352         &c_emdash,      "em",
    353         &c_rule,        "ru",
    354         &c_minus,       "\\-",
    355         &c_fi,          "fi",
    356         &c_fl,          "fl",
    357         &c_ff,          "ff",
    358         &c_ffi,         "Fi",
    359         &c_ffl,         "Fl",
    360         &c_acute,       "aa",
    361         &c_grave,       "ga",
    362         &c_under,       "ul",
    363         &c_rooten,      "rn",
    364         &c_boxrule,     "br",
    365         &c_lefthand,    "lh",
    366         &c_dagger,      "dg",   /* not in nroff?? */
    367         &c_isalnum,     "__",
    368         0, 0
    369 };

Is the troff that has them pulling them in from a font description file
or does it have them hard-coded?
