Dear Vint,

Would you **please** consider that Arabic Language is not the only 
language which  uses Arabic-Script. Some countries such as Iran using 
both sets because 4-5-6 look different in two sets.
A registry for the security reasons may prohibit the Digit-Mixing , but 
the domain's owner  may want to mix it to attract the market.
 For example : please visit   ش_/*۴٤*/_.تست.کام .   Is it really fare to 
prohibit it ?
