Hello Alan & Magnus.

Sorry for you confusion.
I did many copy actions and rename actions.
So you may see, I added unexpected code into non AIX platform.

I think I should not put 2 kind of modification.

For this bug id, I'll handle IBM964 and IBM33722.
(also SimpleEUCEncoder.java is required)

I'll submit code review again.

Additionally, I'll touch

I'll not touch

My build machine is not so fast, after test is done.
I'll post new code.
