Helllo @naotoj .
I used `System.console()` and `Console.charset()`.

The following executables had same issue, I fixed them.
> jar.exe, javac.exe, javadoc.exe, javap.exe, jdeps.exe, jlink.exe, jmod.exe, jpackage.exe

I could not find out the following executables had same issue or not
> jabswitch.exe, jcmd.exe, jfr.exe, jhsdb.exe, jimage.exe, jinfo.exe, jmap.exe, jps.exe, jrunscript.exe, jstack.exe, jstat.exe, jstatd.exe, kinit.exe, klist.exe, ktab.exe

The following executables worked fine.
> jarsigner.exe, java.exe, javaw.exe, jdb.exe, jdeprscan.exe, jshell.exe, keytool.exe, rmiregistry.exe, serialver.exe

The following executables were GUI apps
> jaccessinspector.exe, jaccesswalker.exe, jconsole.exe

These fixes don't have testcases.
Do you have any idea about testcase for this issue ?
