8368845: x-IBM930 uses incorrect character for Hex 42 60

[naotoj]

Fixing a charset en/decoder for x-IBM930. There was a "temporary" mapping for the said code point for the backward compatibility (as of JDK7). Since the issue requests the "correct" mapping, I believe we can replace the temporary one with the correct mapping.

Should we add a test to confirm the swap to the new behavior?

Should we add a test to confirm the swap to the new behavior?

I had added the test data for the new mapping (Cp930.b2c) which is used for several test cases. Added the bug id to the relevant tests which should make it clearer.
