I cannot copy sites where url is IDN type
like 

eladó.hu
házak.hu

I get always error like:
20:44:12 Error:  "Connect Error" (-4) after 2 retries at link xn--elad-tqa.hu/
(from primary/primary)
20:44:12 Warning:  No data seems to have been transferred during this session!
: restoring previous one!

Anyone can help how to copy such sites?
