Bug #9245: Kernel::system gives wrong output for utf-8 characters on windows under utf-8 console
https://bugs.ruby-lang.org/issues/9245

Author: leifcr (Leif Ringstad)
Status: Open
Priority: Normal

Target version: 
ruby -v: ruby 2.0.0p353 (2013-11-22) [i386-mingw32]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


Under windows console running in utf-8 mode (chcp 65001), it is expected to print utf-8 encoded characters in a script from system calls correctly.

To reproduce, create a file in utf-8 format running this:
---
# test.rb
# encoding: UTF-8
system "echo abcæøå"
---

output:
Make sure to set utf-8 console on windows
> chcp 65001 
> ruby test.rb
abc??¦??¸??¥ 

The expected output is:
abcæøå

Running the following on a command prompt gives the correct output:
> ruby -e "system 'echo abcæøå'"

abcæøå

The problem comes clear when running other Windows commands through command line parameters e.g:
system("notepad.exe abcæøå.txt")

Notepad will complain not finding the file abc??¦??¸??¥.txt instead of abcæøå.txt 

It seems that there is an internal encoding done before running the command.
