>> Changing the charset initialization of `java.io.Console` class, which is the basis of `java.io.IO`, so that it would behave the same way as `System.out` wrt encoding. This change will also have the capability to override the default charset used in `IO` methods with `stdout.encoding` system property. A corresponding CSR has also been drafted.

Suggestion:

     * {@systemProperty stdout.encoding}.


This defines the anchor with the same id, and also makes this property available for javadoc index search. Example includes the system property at https://download.java.net/java/early_access/jdk24/docs/api/java.base/java/lang/ClassLoader.html#java.system.class.loader
