/**
* <p>
* Tests support for the typical U.S. EBCDIC encoding.
* Unfortunately this test exposes a <a target="_top" href=
* "http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4867251">bug<a/>
* in the handling of NEL, character 0x85, in Sun's JDK. Specifically
* InputStreamReader maps 0x85 to a line feed rather than
* NEL. I've reported the bug to the Java Developer Connection,
* but until it's fixed this test fails. I don't have an easy
* workaround.
