+\subsection{Supported tar formats \label{tar-formats}}
+
+There are three tar formats that can be created with the \module{tarfile}
+module:
+
+\begin{itemize}
+
+\item
+The \POSIX{}.1-1988 ustar format (\constant{USTAR_FORMAT}). It supports
+filenames up to a length of at best 256 characters and linknames up to 100
+characters. The maximum file size is 8 gigabytes. This is an old and limited
+but widely supported format.
+
+\item
+The GNU tar format (\constant{GNU_FORMAT}). It supports long filenames and
+linknames, files bigger than 8 gigabytes and sparse files. It is the de facto
+standard on GNU/Linux systems. \module{tarfile} fully supports the GNU tar
+extensions for long names, sparse file support is read-only.
+
+\item
+The \POSIX{}.1-2001 pax format (\constant{PAX_FORMAT}). It is the most
+flexible format with virtually no limits. It supports long filenames and
+linknames, large files and stores pathnames in a portable way. However, not
+all tar implementations today are able to handle pax archives properly.
+
+The \emph{pax} format is an extension to the existing \emph{ustar} format. It
+uses extra headers for information that cannot be stored otherwise. There are
+two flavours of pax headers: Extended headers only affect the subsequent file
+header, global headers are valid for the complete archive and affect all
+following files. All the data in a pax header is encoded in \emph{UTF-8} for
+portability reasons.
+
+\end{itemize}
+
+There are some more variants of the tar format which can be read, but not
+created:
+
+\begin{itemize}
+
+\item
+The ancient V7 format. This is the first tar format from \UNIX{} Seventh
+Edition, storing only regular files and directories. Names must not be longer
+than 100 characters, there is no user/group name information. Some archives
+have miscalculated header checksums in case of fields with non-\ASCII{}
+characters.
+
+\item
+The SunOS tar extended format. This format is a variant of the \POSIX{}.1-2001
+pax format, but is not compatible.
+
+\end{itemize}
+
+%----------------
+% Unicode issues
+%----------------
+
+\subsection{Unicode issues \label{tar-unicode}}
+
+The tar format was originally conceived to make backups on tape drives with the
+main focus on preserving file system information. Nowadays tar archives are
+commonly used for file distribution and exchanging archives over networks. One
+problem of the original format (that all other formats are merely variants of)
+is that there is no concept of supporting different character encodings.
+For example, an ordinary tar archive created on a \emph{UTF-8} system cannot be
+read correctly on a \emph{Latin-1} system if it contains non-\ASCII{}
+characters. Names (i.e. filenames, linknames, user/group names) containing
+these characters will appear damaged.  Unfortunately, there is no way to
+autodetect the encoding of an archive.
+
+The pax format was designed to solve this problem. It stores non-\ASCII{} names
+using the universal character encoding \emph{UTF-8}. When a pax archive is
+read, these \emph{UTF-8} names are converted to the encoding of the local
+file system.
+
+The details of unicode conversion are controlled by the \var{encoding} and
+\var{errors} keyword arguments of the \class{TarFile} class.
+
+The default value for \var{encoding} is the local character encoding. It is
+deduced from \function{sys.getfilesystemencoding()} and
+\function{sys.getdefaultencoding()}. In read mode, \var{encoding} is used
+exclusively to convert unicode names from a pax archive to strings in the local
+character encoding. In write mode, the use of \var{encoding} depends on the
+chosen archive format. In case of \constant{PAX_FORMAT}, input names that
+contain non-\ASCII{} characters need to be decoded before being stored as
+\emph{UTF-8} strings. The other formats do not make use of \var{encoding}
+unless unicode objects are used as input names. These are converted to
+8-bit character strings before they are added to the archive.
+
+The \var{errors} argument defines how characters are treated that cannot be
+converted to or from \var{encoding}. Possible values are listed in section
+\ref{codec-base-classes}. In read mode, there is an additional scheme
+\code{'utf-8'} which means that bad characters are replaced by their
+\emph{UTF-8} representation. This is the default scheme. In write mode the
+default value for \var{errors} is \code{'strict'} to ensure that name
+information is not altered unnoticed.
