Encoding::UndefinedConversionError: "\xA8" from ASCII-8BIT to UTF-8 (SFTP)

Question

Using the Net-SFTP gem, Ruby 2 and Rails 4 I wrote code that was working in pure ruby, but copied my code over to rails and now I get: ``` Encoding::UndefinedConversionError: "\xA8" from ASCII-8BIT to UTF-8 ``` What can I change in my code to get this working? ``` def self.get_recent_file(ftp_file, local_file) Net::SFTP.start(Config::A_FTP[:domain], Config::A_FTP[:username], :password => Config::A_FTP[:password]) do |sftp| sftp.download!(ftp_file, local_file) end end ``` Log ``` Encoding::UndefinedConversionError: "\xA8" from ASCII-8BIT to UTF-8 from /usr/local/opt/rbenv/versions/2.1.0-rc1/lib/ruby/gems/2.1.0/gems/net-sftp-2.1.2/lib/net/sftp/operations/download.rb:339:in `write' from /usr/local/opt/rbenv/versions/2.1.0-rc1/lib/ruby/gems/2.1.0/gems/net-sftp-2.1.2/lib/net/sftp/operations/download.rb:339:in `write' from /usr/local/opt/rbenv/versions/2.1.0-rc1/lib/ruby/gems/2.1.0/gems/net-sftp-2.1.2/lib/net/sftp/operations/download.rb:339:in `on_read' from /usr/local/opt/rbenv/versions/2.…

Accepted Answer

This helps me:

```
def self.get_recent_file(ftp_file, local_file)
  local_io = File.new(local_file, mode: 'w', encoding: 'ASCII-8BIT')
  Net::SFTP.start(Config::A_FTP[:domain], Config::A_FTP[:username], :password => Config::A_FTP[:password]) do |sftp|
    sftp.download!(ftp_file, local_io)
  end
  local_io.close
end
```
