+\section{Listing characters in a font}
+
+We can use \texttt{cpdf} to find out which characters are available in a given font, and to print the map between character codes, unicode codepoints, and Adobe glyph names. This is presently a best-effort service, and does not cover all font/encoding types.
+
+We find the name of the font by using \texttt{-list-fonts}:
+
+{\small\begin{verbatim}
+$ ./cpdf -list-fonts cpdfmanual.pdf 1
+1 /F46 /Type1 /XYPLPB+NimbusSanL-Bold 
+1 /F49 /Type1 /MCBERL+URWPalladioL-Roma 
+\end{verbatim}}
+
+We may then print the table, giving either the font's name (e.g \texttt{/F46}) or basename (e.g \texttt{/XYPLPB+NimbusSanL-Bold}):
+
+{\small\begin{verbatim}
+$ ./cpdf -print-font-table /XYPLPB+NimbusSanL-Bold
+         -print-font-table-page 1 cpdfmanual.pdf
