<div>This is more or less a continuation of the thread at <a href="http://tug.org/pipermail/xetex/2010-October/018741.html">http://tug.org/pipermail/xetex/2010-October/018741.html</a>. Unfortunately, I don't know how to include this message in that thread, since I don't actually receive email from this list. Please excuse me. Anyway, Khaled's suggestion from that thread worked; using the following source, Greek and Latin characters appear in the desired font within math mode.</div>

<div>\begin{document}</div><div>Since $X$ is club in $\kappa$, so is the derivative $X\prime$. Therefore each superset of $X'$ is stationary. Blah blah. It follows that $\{\xi < \kappa : \xi \text{ is Mahlo} \} \supseteq \{\xi < \kappa : \xi \text{ is the } \xi^{\text{th}} \text{ Mahlo} \}$ is stationary in $\kappa$, and that $\kappa$ is the $\kappa^{\hspace{0.2mm}\text{th}} \text{ Mahlo}$.</div>
<div>\end{document}</div></div><div><br></div><div>Yet, as you'll see if you compile it, the primes are tiny and misplaced. (The related thread from a few days ago, at <a href="http://tug.org/pipermail/xetex/2010-October/018636.html">http://tug.org/pipermail/xetex/2010-October/018636.html</a>, isn't helping me here.) Furthermore, if in the final line of the preamble one uses, say, Minion Pro instead of Libertine, the primes vanish. If the issue is that unicode-math is looking for the prime glyph in Libertine (or Minion, as the case may be) how can I tell it to look in XITS instead? Also, as I feared would happen, the kerning on exponents, commas, and the like isn't ideal. Is there a way to get around this that's more efficient than tweaking hspace as needed?</div>
