8131664: Javadoc for PrintStream is now incorrect

[Brian Burkhalter]

https://bugs.openjdk.java.net/browse/JDK-8131664 <https://bugs.openjdk.java.net/browse/JDK-8131664>
http://cr.openjdk.java.net/~bpb/8131664/webrev.00/ <http://cr.openjdk.java.net/~bpb/8131664/webrev.00/>

This patch proposes to clean up some verbiage in java.io <http://java.io/>.PrintStream with respect to the encoding being used to convert chars to bytes.

Thanks,

Brian
