[Dnsmasq-discuss] Filtering non-latin1 or non-ASCIII dns requests?

[Petr Menšík]

I think there might be a way to reject all IDN names, which start with 
xn-- prefix. Which is present in all ascii forms of incoming names, 
which contain non-ascii characters, encoded in IDN 2008. That might 
help. I am not sure there is existing option to block any name 
containing such label.
