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.

If a target mapping in the decoding map occurs multiple times, then that target is mapped to None (undefined mapping), causing an exception when encountered by the charmap codec during translation.
