The io.encodings vocabulary provides utilities for encoding and decoding bytes that represent text. Encodings can be used in the following situations:

•	With binary input streams, to convert bytes to characters
•	With binary output streams, to convert characters to bytes
•	With byte arrays, to convert bytes to characters
•	With strings, to convert characters to bytes

Encoding descriptors
Manually constructing an encoded stream
Encoding and decoding strings

New types of encodings can be defined:
Encoding protocol

Setting encodings on the current streams:

encode-output ( encoding -- )

decode-input ( encoding -- )

Setting encodings on streams:

re-encode ( stream encoding -- newstream )

re-decode ( stream encoding -- newstream )

Combinators to change the encoding:

with-encoded-output ( encoding quot -- )

with-decoded-input ( encoding quot -- )
