Console is supposed to be a "char/String" based class, "encoding" really 
have no business here in its api. Simply for some implementation convenience
is really not a good reason to add such a public method.

That said, I would be fine to have such informative info in the system 
together with its siblings, file,encoding and another "supposed to be 
property sun.jnu.encoding.
