That's a bug then (3.0.1)

octave> x=0:.2:6; y1 = sin(x); y2 = cos(x);
octave> plot(x,y1,x,y2)
octave> legend("sin(x)", "cos(x)")
octave> get(get(gca,"children")(1),"keylabel")
ans = sin(x)

ans = cos(x)


set (findobj (gca, "-property", "keylabel"), "interpreter",   "none")

stopped rendering Greek, but underscores still yield subscripted characters.

HTML <pre> means pre-formatted. Is there a way in TeX to stop TeX
interpretation of part of a string?
