Subject: [ruby-core:70217] [Ruby trunk - Bug #11412] [Open] Filename	encoding issues (Windows)

Issue #11412 has been reported by Daniel Frank.

----------------------------------------
Bug #11412: Filename encoding issues (Windows)
https://bugs.ruby-lang.org/issues/11412

* Author: Daniel Frank
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: ruby 2.2.2p95 (2015-04-13 revision 50295) [x64-mingw32]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
Ruby is apparently unable to find files it just told me are there (containing japanese characters).
Demo code:
Dir.foreach('.') do |entry|
	puts "#{entry} exists? " + File.exist?(entry).to_s
end

Output:
C:\tmp\test\filenames>C:\tmp\rubybackup\ruby-2.2.2-x64-mingw32\bin\ruby.exe test.rb
. exists? true
.. exists? true
a.md exists? true
b.txt exists? true
test.rb exists? true
???.txt exists? false

Directory contents according to cmd.exe/dir:
02.08.2015  22:18    <DIR>          .
02.08.2015  22:18    <DIR>          ..
02.08.2015  22:04                 0 a.md
02.08.2015  22:04                 0 b.txt
02.08.2015  22:20                87 test.rb
02.08.2015  22:04                 0 ???.txt

The undisplayable filename contains japanese characters and should read: ���������.txt

C:\tmp\test\filenames>chcp
Active code page: 850

Attached zip file contains all files necessary to see the problem (with the exception of the script the files have a size of zero bytes).
