\section{Introduction} % I.1

In the most recent review of this document, proposals were encouraged
to include a reference implementation where possible.  Where an
implementation requires system specific knowledge it was documented.

This appendix contains the reference implementations that have been
accepted by the committee.  This is not a complete reference
implementation nor do the committee recommend these implementations.
They are supplied solely for the purpose of providing a detailed
understanding of a definitions requirement.  System implementors are
free to implement any operation in a manner that suits their system,
but it must exhibit the same behavior as the reference implementation
given here.

\section{The optional Extended-Character word set} % I.18
\label{imp:xchar}

This reference implementation assumes the UTF-8 character encoding
is being used.
