Release Note: New System Properties for `System.out` and `System.err`

Two new system properties, `stdout.encoding` and `stderr.encoding`, have been added. The value of these system properties is the encoding used by the standard output and standard error streams (`System.out` and `System.err`).

The default values of these system properties depend on the platform. The values take on the value of the `native.encoding` property when the platform does not provide streams for the console. The properties can be overridden on the launcher's command line option (with `-D`) to set them to `UTF-8` where required.
