IDNA not supported

[eterry1388]

When this is called:

nslookup "à±<8a>#001a.t-mobile.com"

I get:

E, [2016-09-09T13:37:21.121431 #20408] ERROR -- : Actor crashed!
Encoding::CompatibilityError: inspected result must be ASCII only or use the default external encoding

My workaround was to put this code:

unless name.encoding.to_s == 'UTF-8'
  puts "Bad encoding for #{name} , which was #{name.encoding}"
  transaction.fail!( :NXDomain )
  return
end

before this line:

transaction.passthrough!( @resolver )
