Some IBM EBCDIC machines need converters for codepage 1047.
Two new converters "src/share/sun/sun/io/CharToByteCp1047.java" and
"src/share/sun/sun/io/ByteToCharCp1047.java" are included. I
suspect that the file "src/share/sun/sun/io/CharacterEncoding.java" ought to
be updated too, although the IBM developers who needed the new codepage have
not done this.
I've attached CharToByteCp1047.java.gz and ByteToCharCp1047.java.gz
to this bug report.
