Bug #12650: Use UTF-8 encoding for ENV on Windows
https://bugs.ruby-lang.org/issues/12650

* Author: Dvis Mosns
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.4.0dev (2016-08-02 trunk 55799) [x64-mswin64_140]
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
Windows environment variables supports Unicode (same wide WinAPI) and so there's no reason to limit ourselves to any codepage.
Currently ENV would use locale's encoding (console's codepage) which obviously won't work correctly for characters outside of those codepages.

I've attached a patch which implements this and fixes bug #9715
