 * <p> A <i>charset</i> is named mapping between sequences of
 * sixteen-bit Unicode characters and sequences of bytes, in the sense
 * defined in <a
 * href="http://www.ietf.org/rfc/rfc2278.txt"><i>RFC&nbsp;2278</i></a>.
 * A <i>decoder</i> is an engine which transforms bytes in a specific
 * charset into characters, and an <i>encoder</i> is an engine which
 * transforms characters into bytes.  Encoders and decoders operate on
 * byte and character buffers.  They are collectively referred to as
 * <i>coders</i>.
 *
 * <p> The {@link java.nio.charset.Charset} class defines methods for
 * creating coders for a given charset and for retrieving the various
 * names associated with a charset.  It also defines static methods
 * for testing whether a particular charset is supported, for locating
 * charset instances by name, and for constructing a map that contains
 * every charset for which support is available in the current Java
 * virtual machine.
 *
 * <p> Most users will not use these classes directly; instead they
 * will use the existing charset-related constructors and methods in
 * the {@link java.lang.String} class, together with the existing
 * {@link java.io.InputStreamReader} and {@link
 * java.io.OutputStreamWriter} classes, all of whose implementations
 * have been reworked to make use of the charset facilities defined in
 * this package.  A small number of changes have been made to the
 * {@link java.io.InputStreamReader} and {@link
 * java.io.OutputStreamWriter} classes in order to allow explicit
 * charset objects to be specified in the construction of instances of
 * those classes.
 *
 * <p> Support for new charsets can be made available via the
 * interface defined in the {@link
 * java.nio.charset.spi.CharsetProvider} class in the {@link
 * java.nio.charset.spi} package.
 *
 * <p> Unless otherwise noted, passing a {@code null} argument to a
 * constructor or method in any class or interface in this package
 * will cause a {@link java.lang.NullPointerException
 * NullPointerException} to be thrown.
