It is not clear if `WindowsHelper` is an appropriate place for this utility (`BasicTest` is not Windows-specific), I've assumed that `--temp` flag itself is only used on Windows.

I don't think it is good that the encoding of jpackage output depends on the default jvm encoding. It is convenient to know that the output is always in a specific encoding regardless of the values of `user.language` and `user.country` system properties. But this might not be the case of help and error output produced by jpackage.

Let's keep jpackage aligned with other JDK tools. Could you please check the behavior of `java`? How the output of `java --help` is encoded?
