Fix Java Execution + Support UF8 strings

[mhatano]

Quick fix for the issue #1166, Java build in non-English editions of Windows will result garbled message, stdout and stderr displayed.
Please note that this fix would have further issue: if user's final target deployment would have different encodings from all-UTF-8 setup, (such as "normal" Windows cmd.exe, they normally have ANSI encodings for average users) so testing and evaluating might become more difficult.)

Steps to reproduce:
　　Atom: 1.57.0 (Windows x64)
Script: 3.31.3
Grammar: java.js
Java: AdoptOpenJDK 11.0.9.1 (HotSpot)

Hello: I am using Atom as well with Java and brand new install of JDK

Still getting this error even though it runs on VScode:
error: invalid flag: Projects\My Usage: javac <options> <source files> use --help for a list of possible options

I am not understanding how to fix this @aminya. It looks like you have the fix, but I am unsure how to fix this. Any help is appreciated.
