/**
 * Charset service-provider class.
 *
 * <p> A charset provider is a concrete subclass of this class that has a
 * zero-argument constructor and some number of associated charset
 * implementation classes.  Charset providers may be installed in an instance
 * of the Java platform as extensions.  Providers may also be made available by
 * adding them to the applet or application class path or by some other
 * platform-specific means.  Charset providers are looked up via the current
 * thread's {@link java.lang.Thread#getContextClassLoader() context class
 * loader}.
 *
 * <p> A charset provider identifies itself with a provider-configuration file
 * named {@code java.nio.charset.spi.CharsetProvider} in the resource
 * directory {@code META-INF/services}.  The file should contain a list of
 * fully-qualified concrete charset-provider class names, one per line.  A line
 * is terminated by any one of a line feed ({@code '\n'}), a carriage return
 * ({@code '\r'}), or a carriage return followed immediately by a line feed.
 * Space and tab characters surrounding each name, as well as blank lines, are
 * ignored.  The comment character is {@code '#'} (<code>'&#92;u0023'</code>); on
 * each line all characters following the first comment character are ignored.
 * The file must be encoded in UTF-8.
 *
 * <p> If a particular concrete charset provider class is named in more than
 * one configuration file, or is named in the same configuration file more than
 * once, then the duplicates will be ignored.  The configuration file naming a
 * particular provider need not be in the same jar file or other distribution
 * unit as the provider itself.  The provider must be accessible from the same
 * class loader that was initially queried to locate the configuration file;
 * this is not necessarily the class loader that loaded the file. </p>
