AFAIK, PDF's /ActualText tag is what you are lokking for, though not
every PDF reader support it (Poppler-based reaaders don't for example).

\documentclass{article}

\usepackage{xltxtra}
\setromanfont{Adobe Garamond Pro}
\usepackage{accsupp}

\newcommand{\asterism}{%
        \BeginAccSupp{method=hex,unicode,ActualText=2042}%
                \raisebox{-.15em}{%
                        \setlength{\tabcolsep}{0.05em}%
                        \begin{tabular}{@{}cc@{}}%
                                \multicolumn2c*\\[-.75em]*&*%
                        \end{tabular}%
                }%
        \EndAccSupp{}%
}

\begin{document}

This \asterism\ is an asterism.
