. A fundamental property of the DNS is that it is an exact-match lookup service. For a given query, either there is a single name that matches or there is no match. When two domain names are identical in appearance except for ordinary typographic style variations (which, at present, have no equivalent for emoji), but have different underlying code points, they identify two different DNS domains.
While all true, the above fundamental properties do not apply to e-mail addresses - which is what "mailbox" name in the subject line refers to. Apart from that point, many of your arguments could be applied to e-mail addresses. What is missing is writing an actual statement that extracts from the useful statements posted here bye various people a single statement that squarely addresses the issue in the framework of email addresses and that could be the formal position of UASG on why or to what degree emoji fall outside the universal acceptance scope. BTW, the argument made by some people here that they represent an "inferior form" (my term) of communication compared to natural languages is rather weak and I prefer not to rely on it. A./
