@evan with activitypub actors, is there any standard which limits valid characters in account names? I want to allow emojis on my service, but idk if this will federate properly to other services.
Also it looks like mastodon treats these as immutable (the account name is in the account uri) - I think users should be able to change their account name but I worry this won't federate properly.
@uc in terms of what characters you can use, ActivityPub does not limit what can be in the preferredUsername property. However, if it's used as the username part of a Webfinger address, like Mastodon does, there are some restrictions:

I hope that helps!
Yes, this is helpful, thank you!
It looks like I can at least support it in my own software and see how mastodon behaves
@uc @trwnh and I are working on the #SocialCG report on using ActivityPub with Webfinger so any other questions in this area would be really helpful to capture here https://github.com/swicg/activitypub-webfinger/issues
