% \begin{abstract}
% Package \xpackage{listings} does not support files with multi-byte
% encodings such as UTF-8. In case of \cs{lstinputlisting} a simple
% workaround is possible if an one-byte encoding exists that the file
% can be converted to. Also \eTeX\ and \pdfTeX\ regardless of its mode
% are required.
% \end{abstract}
%
% \tableofcontents
%
% \section{Documentation}
%
% \subsection{User interface}
%
% Load this package after or instead of package \xpackage{listings}
% \cite{listings}.
% The package does not define own options and passes given options to
% package \xpackage{listings}.
%
% The syntax of package \xpackage{listings}' key \xoption{inputencoding}
% is extended:
% \begin{quote}
%   |inputencoding=utf8/|\meta{one-byte-encoding}\\
%   Example: |inputencoding=utf8/latin1|
% \end{quote}
% That means the file is encoded in UTF-8 and can
% be converted to the given \meta{one-byte-encoding}.
% The available encodings for \meta{one-byte-encoding} are
% listed in section ``1.2 Supported encodings'' of
% package \xpackage{stringenc}'s documentation \cite{stringenc}.
% Of course, the encoding must encode its characters with
% one byte exactly. This excludes the unicode encodings
% (\xoption{utf8}, \xoption{utf16}, \dots).
%
% Only \cs{lstinputlisting} is supported by the syntax extension
% of key \xoption{inputencoding}.
%
% Internally package \xpackage{listingsutf8} reads the file as binary file
% via primitives of \pdfTeX\ (\cs{pdffiledump}). Then the file
% contents is converted as string using package \xpackage{stringenc} and
% finally the string is read as virtual file by \eTeX's \cs{scantokens}.
%
% \subsection{Future}
%
% Workarounds are not provided for
% \begin{itemize}
% \item \cs{lstinline}
% \item Environment |lstlisting|.
% \item Environments defined by \cs{lstnewenvironment}.
% \end{itemize}
% Perhaps someone will find time to extend package \xpackage{listings}
% with full native support for UTF-8. Then this package would become obsolete.

% \section{Installation}
%
% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\url{ftp://ftp.ctan.org/tex-archive/}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/oberdiek/listingsutf8.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/listingsutf8.pdf}] Documentation.
% \end{description}
%
%
% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
% are also available in a TDS compliant ZIP archive. There
% the packages are already unpacked and the documentation files
% are generated. The files and directories obey the TDS standard.
% \begin{description}
% \item[\CTAN{install/macros/latex/contrib/oberdiek.tds.zip}]
% \end{description}
% \emph{TDS} refers to the standard ``A Directory Structure
% for \TeX\ Files'' (\CTAN{tds/tds.pdf}). Directories
% with \xfile{texmf} in their name are usually organized this way.
%
% \subsection{Bundle installation}
%
% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
% TDS tree (also known as \xfile{texmf} tree) of your choice.
% Example (linux):
% \begin{quote}
%   |unzip oberdiek.tds.zip -d ~/texmf|
% \end{quote}
%
% \paragraph{Script installation.}
% Check the directory \xfile{TDS:scripts/oberdiek/} for
% scripts that need further installation steps.
% Package \xpackage{attachfile2} comes with the Perl script
% \xfile{pdfatfi.pl} that should be installed in such a way
% that it can be called as \texttt{pdfatfi}.
% Example (linux):
% \begin{quote}
%   |chmod +x scripts/oberdiek/pdfatfi.pl|\\
%   |cp scripts/oberdiek/pdfatfi.pl /usr/local/bin/|
% \end{quote}
%
% \subsection{Package installation}
%
% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
% \docstrip\ archive. The files are extracted by running the
% \xfile{.dtx} through \plainTeX:
% \begin{quote}
%   \verb|tex listingsutf8.dtx|
% \end{quote}
%
% \paragraph{TDS.} Now the different files must be moved into
% the different directories in your installation TDS tree
% (also known as \xfile{texmf} tree):

% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
% TDS installing feature, then some files can already be in the right
% place, see the documentation of \docstrip.
%
% \subsection{Refresh file name databases}
%
% If your \TeX~distribution
% (\teTeX, \mikTeX, \dots) relies on file name databases, you must refresh
% these. For example, \teTeX\ users run \verb|texhash| or
% \verb|mktexlsr|.
%
% \subsection{Some details for the interested}
%
% \paragraph{Attached source.}
%
% The PDF documentation on CTAN also includes the
% \xfile{.dtx} source file. It can be extracted by
% AcrobatReader 6 or higher. Another option is \textsf{pdftk},
% e.g. unpack the file into the current directory:
% \begin{quote}
%   \verb|pdftk listingsutf8.pdf unpack_files output .|
% \end{quote}
%
% \paragraph{Unpacking with \LaTeX.}
% The \xfile{.dtx} chooses its action depending on the format:
% \begin{description}
% \item[\plainTeX:] Run \docstrip\ and extract the files.
% \item[\LaTeX:] Generate the documentation.
% \end{description}
% If you insist on using \LaTeX\ for \docstrip\ (really,
% \docstrip\ does not need \LaTeX), then inform the autodetect routine
% about your intention:
% \begin{quote}
%   \verb|latex \let\install=y\input{listingsutf8.dtx}|
% \end{quote}
% Do not forget to quote the argument according to the demands
% of your shell.
%
% \paragraph{Generating the documentation.}
% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
% the documentation. The process can be configured by the
% configuration file \xfile{ltxdoc.cfg}. For instance, put this
% line into this file, if you want to have A4 as paper format:
% \begin{quote}
%   \verb|\PassOptionsToClass{a4paper}{article}|
% \end{quote}
% An example follows how to generate the
% documentation with pdf\LaTeX:
% \begin{quote}
%\begin{verbatim}
%pdflatex listingsutf8.dtx
%makeindex -s gind.ist listingsutf8.idx
%pdflatex listingsutf8.dtx
%makeindex -s gind.ist listingsutf8.idx
%pdflatex listingsutf8.dtx
%\end{verbatim}
% \end{quote}
