Bug #9712: Dir.entries replace Unicode character with questionmarks
https://bugs.ruby-lang.org/issues/9712

* Author: Thomas Thomassen
* Status: Open
* Priority: High
* Assignee: cruby-windows
* Category: platform/windows
* Target version: current: 2.2.0
* ruby -v: ruby 2.2.0dev (2014-04-07 trunk 45528) [i386-mswin32_100]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
My basis when testing this is that I have a computer with English OS - codepage Windows-1252. The tests might yield different result if the Windows codepage is different - so please pay attention to that if you are unable to reproduce.

Given a folder named "Foo" which contains a sub-folder "Ƥ" ("\u3066\u3059\u3068") Dir.entries("Foo") will return:
[".", "..", "???"]

The characters that doesn't fit my filesystem codepage is translated into question marks.

I would have expected the strings returned to be in some Unicode format.
