<i18n dev> RFR: 8232846: ProcessHandle.Info command with non-English shows question marks

[Toshio 5 Nakamura]

Hi All,

Could you review this change? Additionally, I'd like to ask a sponsor for
it, since I'm not a committer.

Bug: https://bugs.openjdk.java.net/browse/JDK-8232846
Webrev: http://cr.openjdk.java.net/~tnakamura/8232846/webrev.00

Under Windows environments, ProcessHandle.Info.command shows question marks
if the command has non-English characters. I'd like to change the
underlying API to Unicode version.
Tier1 tests passed.

Best regards,
Toshio Nakamura
