Description

Problem

It seems that system({}, ...) breaks nonascii ENV["PATH"] after execution.
system(...) isn't affected. Only system(env, ...) is affected.

OS: Windows 7
Ruby: https://github.com/oneclick/rubyinstaller2/releases/download/RubyInstaller-2.6.1-1/rubyinstaller-2.6.1-1-x64.exe
chcp: 現在のコード ページ: 932

Expected

system({}, ...) doesn't break nonascii ENV["PATH"] environment variable after execution.

Actual

Here is the sample code to reproduce this issue.

cat break-env-system.rb
# coding: cp932
ENV["PATH"] = [
  "インストール",
  ENV["PATH"],
].join(File::PATH_SEPARATOR)

env = {}
p ENV["PATH"]
system(env, "echo")
p ENV["PATH"]

It produces the following output:

"インストール;%SystemRoot%\\system32\\WindowsPowerShell\\v1.0\\;C:\\Windows\\system32;C:\\Windows;C:\\Windows\\System32\\Wbem;C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\;C:\\Program Files (x86)\\Windows Kits\\8.1\\Windows Performance Toolkit\\;C:\\Program Files\\CMake\\bin;C:\\GnuWin32\\bin;C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\;C:\\Program Files\\patch-2.5.9-7-bin\\bin;C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\;C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\;C:\\Ruby26-x64\\bin"
ECHO は <ON> です。
"?C???X?g?[??;%SystemRoot%\\system32\\WindowsPowerShell\\v1.0\\;C:\\Windows\\system32;C:\\Windows;C:\\Windows\\System32\\Wbem;C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\;C:\\Program Files (x86)\\Windows Kits\\8.1\\Windows Performance Toolkit\\;C:\\Program Files\\CMake\\bin;C:\\GnuWin32\\bin;C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\;C:\\Program Files\\patch-2.5.9-7-bin\\bin;C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\;C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\;C:\\Ruby26-x64\\bin"

If system("echo") is used instead of system({}, "echo"), ENV["PATH"] is not broken.
