Non ascii characters not handled properly

[olivernaaris]

I have a issue when I try to use non ascii characters, like for example Japanese characters.
Script that I used to test:

require 'winrm'

opts = {
endpoint: "http://???:5985/wsman",
user: "ア ウェブ",
password: "?????",
overall_timeout: 15,
retry_limit: 3,
retry_delay: 10
}

conn = WinRM::Connection.new(opts)
conn.shell(:powershell) do |shell|
output = shell.run("$PSDefaultParameterValues['Out-File:Encoding'] = 'utf8'") do |stdout, stderr|
STDOUT.print stdout
STDERR.print stderr
end
puts "The script exited with exit code #{output.exitcode}"
end

And error:

thanks. #55 appears to be a dupe, but it includes a proposed fix, closing in favor of that one
