Hi Abdulrahman,

As I understand it, these sites are merely records of policy; no
restrictions are imposed. So if .newtld decided to register with IANA to
say "we accept every character", then the tables would duly record that
fact, despite there being a big potential problem.

So, unless I have missed something, such lists are of no help in this
