+To simply access to the various codecs, the module provides these
+additional functions which use \function{lookup()} for the codec

+
+\begin{funcdesc}{getencoder}{encoding}
+Lookup up the codec for the given encoding and return its encoder
+function.
+
+Raises a \exception{LookupError} in case the encoding cannot be found.

+Raises a \exception{LookupError} in case the encoding cannot be found.
+\end{funcdesc}

+\begin{funcdesc}{getreader}{encoding}
+Lookup up the codec for the given encoding and return its StreamReader

+\begin{funcdesc}{getwriter}{encoding}
+Lookup up the codec for the given encoding and return its StreamWriter
