Yes , both for the jdk1.3.1 and personal java on my machine supports it. And
yes it's in fact  abstract and that abstraction gives me the ability to
forget about the actual Unicode encoding of the file I'm processing. I plan
to use / and use it for Japanese characters. utf-8 encoding is not the best
match for the encoding because most of the kanji and kana encoded in three
bytes. It just makes the file bigger.

put a byte order mark before some unicode characters array representation
and give it to the String constructor with the encoding "Unicode" then
decide if is there really exists or not. Whether it be practical to use or
not is another issue.
