A character stream with byte-character transcoding for its storage or transport format based on the value of ..CharEncoding.
ExternalCharacterStream extends IByteStream because "RawBytes" is an option for ..CharEncoding.
Names the character encoding used to encode this character stream in its storage or transport format
A value of "Native" in this property means the stream is encoded in the native format for the local installation.
Values of "RawBytes" or "Binary" mean that each character is represented by the corresponding byte in the external storage or transport format.
(This property is overridden from %IO.IParts.ByteIO but has a different meaning in this character IO context.)
