Looks up the given encoding and returns a tuple (encoder, decoder,

stream reader, stream writer) of functions which implement the

different aspects of processing the encoding.

The encoding string is looked up converted to all lower-case

characters. This makes encodings looked up through this mechanism
|
|
effectively case-insensitive.

If no codec is found, a KeyError is set and NULL returned.
