You can use these objects to do transparent direct recodings from e.g. latin-1 to utf-8 and back. stream must be a file-like object. encode, decode must adhere to the Codec interface, Reader, Writer must be factory functions or classes providing the StreamReader, StreamWriter interface resp. encode and decode are needed for the frontend translation, Reader and Writer for the backend translation. Unicode is used as intermediate encoding. Error handling is done in the same way as defined for the StreamWriter/Readers.

Note: The wrapped version will only accept the object format defined by the codecs, i.e. Unicode objects for most builtin codecs. Output is also codec dependent and will usually be Unicode as well. Files are always opened in binary mode, even if no binary mode was specified. This is done to avoid data loss due to encodings using 8-bit values. The default file mode is 'rb' meaning to open the file in binary read mode. encoding specifies the encoding which is to be used for the file. errors may be given to define the error handling. It defaults to 'strict' which causes ValueErrors to be raised in case an encoding error occurs. buffering has the same meaning as for the builtin open() API. It defaults to line buffered. The returned wrapped file object provides an extra attribute .encoding which allows querying the used encoding.

Strings written to the wrapped file are interpreted according to the given data_encoding and then written to the original file as string using file_encoding. The intermediate encoding will usually be Unicode but depends on the specified codecs. Strings are read from the file using file_encoding and then passed back to the caller as string using data_encoding. If file_encoding is not given, it defaults to data_encoding. errors may be given to define the error handling. It defaults to 'strict' which causes ValueErrors to be raised in case an encoding error occurs. The returned wrapped file object provides two extra attributes .data_encoding and .file_encoding which reflect the given parameters of the same name. The attributes can be used for introspection by Python programs.
