Files are listing as junk characters

[lakshmi2703]

I am trying to list directory, but it displayed as junk characters. However the same site working without any issues with perl, php
Sample code:
Net::SFTP.start(host, username, :password => password, :port => 22) do |sftp|
sftp.dir.foreach(folder) do |entry|
next if (entry.name == '..' || entry.name == '.')
puts entry.name
end
end
I am getting like this:
�epubtesepubtest��Y��dY���Y����..���epubtesepubtestA�Y��Y�\�Y�I`�

If I code entry.longname
I get exception like this:

Hello,
For what its worth I found this...
https://stackoverflow.com/questions/42124883/broken-filenames-with-ruby-when-connected-to-sftp-version-5

In a nut shell if a particular server is using a protocol version > 3 you can see this behavior (corrupted filenames). I applied the fix (aka hack) of setting the HIGHEST_PROTOCOL_VERSION_SUPPORTED variable to 3 in sftp/session.rb locally and the issue was resolved. Obviously if you deploy this to third party hosting you can't change the source code but at least you can test it.

This seems to be a duplicate of #78.

Net::SFTP v3.0.0 (published a few days ago) now allows (via #107) to do specify the protocol directly via Net::SFTP.start:

Net::SFTP.start(host, user, ssh_options, {version: 3}) do
  # SNIP
end

@lakshmi2703 could you please try out?
