Functions

func Decode 

func Decode(encoding uint16, data []byte) ([]byte, error)

Decode returns a decoded byte slice for the provided data given a specified encoding.

func MagicIdentifier 

func MagicIdentifier() []byte

MagicIdentifier is a function to lazily return the unique identifier of an FFXIV bundle headers based on a known constant. This function will panic if something goes wrong with the computation
