>> 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.
