\section{Substitutions}
The following pages list all ``interesting'' glyph substitutions by
feature. A listing such as
\smallskip
\begin{substitutions*}
U+0024 \char36\\
\quad \texttt{c2sc} $\to$ \XeTeXglyph 1913
\end{substitutions*}
\smallskip
\noindent means that the c2sc feature applies to all scripts and
language systems. A listing such as
\smallskip
\begin{substitutions*}
\UCSchartfont
U+0162 \char354\\
\quad \texttt{c2sc.\textsc{dflt}} $\to$ \XeTeXglyph 873\\
\quad \texttt{c2sc.latn} $\to$ \XeTeXglyph 873\\
\quad \texttt{locl.latn.ROM} $\to$ \XeTeXglyph 198
\end{substitutions*}
\smallskip
\noindent means that the c2sc substitution is only active for
the \textsc{dflt} and latn scripts, but not for the cyrl or grek
scripts, and the locl substitution is only active in the ROM language
system of the latn script.
