\section{The Pigpen cipher}

The \TeX\ Pigpen cipher font is a small hack\footnote{%
	The \TeX\ Pigpen cipher was inspired by a discussion on
	\texttt{comp.text.tex} in December 2008.} 
to type the so-called masonic cipher, or Freemason's cipher,
which is a simple substitution cipher based on a grid. 
A 3x3 grid is filled with the letters A to I and J to R.

The letters in this grid are simply replaced by the inner edges 
of their box within the grid. The subset of letters J to R is marked
by a dot.

The letters S, T, U and V are arranged in the four quadrants of an X,
the letters W, X, Y and Z follow this arragement but are marked with
a dot. Again, the letters are substituted by the inner edges of their
respective corner.
