One last note: maybe it's not just as simple as I suggested? Just  
grabbing the "5F char and printing it doesn't lead to disaster:

\documentclass{article}
\DeclareFontFamily{U}{osx}{}
\DeclareFontShape{U}{osx}{m}{n}{<-> "Hoefler\space Text"}{}
\begin{document}
\fontencoding{U}\fontfamily{osx}\selectfont
test\char"5F
\end{document}

So there's more to it, I guess missing maths metrics and so on...
