UA Colleagues:
We spend a lot of time thinking about universal acceptance of email addresses and URLs. We tend to assume that email addresses and URLs are important. But for a lot of information technology users, they aren't. Those users learned to use IT via mobile, rather than via desktop computers. They use all-embracing messaging apps like WeChat, ...
China is a very large special case, because literally everyone in China has a Wechat acccount and that's their online identity. Statista says they have 1.2 billion active users. To the extent they use e-mail, it's to communicate with people in other countries.
I think a useful response to this might be to keep asking ourselves, how do people communicate in preference to emails? How do people find things in preference to typing in URLs? Then investigating those methods for Universal Acceptance as well.
I would prefer to limit the mission creep here. Mobile apps and walled gardens are targeted by their owners at specific communities (perhaps very large ones, but specific anyway) and I don't see that we have anything useful to tell them. If they consider speakers of language X to be part of their target audience, they'll add support for language X. That's doubly true if the interface they show that audience doesn't contain domain names or e-mail addreses, since those are the only things that UA deals with. R's, John
