 % \subsection{Vulgar fractions}
 % The \cmd\vfrac\ command for setting `vulgar' fractions based on AAT or OpenType font features. Not really recommended for many purposes, depending on your text, but it's a good example of how to program such things using \pkg{fontspec}.
 % \begin{example}
-%   \fontspec{Hoefler Text}
-%   AAT: \vfrac{123}{456}\par
+%   \fontspec{Skia}
+%   AAT: \vfrac{123}{456}\\
 %   \fontspec{Warnock Pro}
 %   ICU: \vfrac{123}{456}
 % \end{example}
 % \noindent (This can be achieved in regular \LaTeX\ with the \pkg{nicefrac} package, but don't believe its name: these fractions aren't nice!)

 % \subsection{Named glyphs}
 % Along the way somewhere, \XeTeX\ added support for selecting glyphs from a TrueType-based OpenType font based on their internal glyph name. Jonathan Kew posted the following definition as a nice interface to it.
