Hi Don, I was just wondering why is Arabic considered different than Unicode@idn.idn in EAIs? Arabic characters are Unicode, and Arabic domain names are also IDN. The only difference is the LTR and RTL reading order, which is probably done by the rendering part, but storing and validating is the same.
