every time the idea of non-ASCII usernames and identifiers comes up, I see a bunch of english speakers talking about how terrible it is that so many systems limit usernames to ASCII and that it's an equitably problem for diverse userbases, and then I look over at actual CJK systems and communities and they all use ASCII for identifiers, and absolutely nobody uses the non-ASCII name support that *does* exist (eg IDN domains) because the UX is intrinsically awful
@rcombs i'm watching a chinese thing now and it seems like they don't mention usernames, they just tell you to go to a platform then search for someone. i don't understand a ton of what they're saying though.
@rcombs i think some services also just don't have usernames, only user ids and display names. e,g, weibo urls look like https://www.weibo.com/u/5618105325. wechat does have usernames though.
@artemist a lot of CJK platforms don't even *have* a concept of unique usernames; there's just an arbitrary numeric ID and a display name
