require 'winrm'

user = "サザ"
pass = 'secret'
end = '1.2.3.4'

opts = {
endpoint: "http://#{end}/wsman",
user: user,
password: pass,
overall_timeout: 5,
retry_limit: 1,
retry_delay: 1
}

conn = WinRM::Connection.new(opts)
conn.shell(:cmd) do |shell|

I'm encountering something that I think is similar. When I send and echo µsomemessage - where µ is a valid character in both UTF-8 and Windows-1252 (my target system's encoding) - I get 'invalid byte sequence' when run from Windows (but behaves okay from macOS/Linux). In particular

• sent from Windows, I get back the Windows-1252 encoding of µ but Ruby thinks it's a UTF-8 string. Under some scenarios where I use the string, I get 'invalid byte sequence' because the Windows-1252 byte sequence of µ isn't a valid UTF-8 byte sequence.
• sent from macOS or Linux, I get back the UTF-8 encoding and the string is expected to be UTF-8. No errors encountered here.

Update: this seems to specifically affect Ruby 2.3 on Windows. Seems fixed under Ruby 2.4.

Hi - looking at the trace of the original issue, this bug is in rubyntlm and should be addressed in WinRb/rubyntlm#56

For @MikaelSmith's issue - glad to hear this is not an issue in ruby 2.4, but if you can reproduce, please provide a stacktrace. Thanks
