| Charset | A charset is a named mapping between Unicode characters and byte sequences. |
| CharsetDecoder | A converter that can convert a byte sequence from a charset into a 16-bit Unicode character sequence. |
| CharsetEncoder | Transforms a sequence of 16-bit Java characters to a byte sequence in some encoding. |
| CoderResult | Used to indicate the result of encoding/decoding. |
| CodingErrorAction | Used to indicate what kind of actions to take in case of encoding/decoding errors. |
| StandardCharsets | Convenient access to the most important built-in charsets. |
| CharacterCodingException | A CharacterCodingException is thrown when an encoding or decoding
error occurs. |
| IllegalCharsetNameException | An IllegalCharsetNameException is thrown when an illegal charset name
is encountered. |
| MalformedInputException | A MalformedInputException is thrown when a malformed input is
encountered, for example if a byte sequence is illegal for the given charset. |
| UnmappableCharacterException | An UnmappableCharacterException is thrown when an unmappable
character for the given charset is encountered. |
| UnsupportedCharsetException | An UnsupportedCharsetException is thrown when an unsupported charset
name is encountered. |
| CoderMalfunctionError | A CoderMalfunctionError is thrown when the encoder/decoder is
malfunctioning. |
