Internationalized Webfinger Handles in ActivityPub
-
@j12t @evan @evanprodromou @jdlh @Edent
I am sorry, but without money and income looking for jobs I am holding off on any deeper fedi involvement rn. It just occurred to me there might be a small and steady no. of TF's around various cross-cutting concerns that neatly slice protocol design space into natural parts, and help attract stakeholders other than devs interested in one particular narrow theme.
More musing out loud..
- Interoperability and extensibility
- Security and privacy
- Connectivity and portability
- Internationalization and localization
- Trust and safety (DEI)
- Fediverse solution developmentThe last one would aggregate initiatives to define building blocks for common business and application domains (Groups, Forums, Geosocial). Particularly well-suited to set up a great web portal around.
For posterity I added this to an existing issue at the SWICG.. https://github.com/swicg/activitypub-api/issues/66

PS. Weird that this time the opengraph preview of the issue carries complete information, including the title.

ActivityPub software usually (but not always!) uses a handle format defined by RFC 7033, Webfinger, which looks like username@domain.example. There’s a ActivityPub and Webfinger report from the Social Web Community Group that details how this interaction works.
All parts of this handle format can include non-ASCII Unicode characters, like accented Latin, Chinese, Arabic, or Hindi scripts. But it takes extra work, so users can’t count on non-ASCII characters being supported in their own or others’ software.
This is a problem for the Fediverse. Of the most-spoken human languages, only three primarily use only ASCII characters (English, Malaysian, Indonesian), for a total of about 500 million people. That means about 90% of humans use languages with non-Latin, or accented, character sets. We are missing an opportunity to include more people worldwide with internationalized handles with names, words and domains in their native languages.
Jim DeLaHunt @jdlh has been doggedly pursuing better support for internationalized Webfinger handles in ActivityPub. To this end, the Social Web Community Group started tracking Internationalized Webfinger Handle Adoption. Covering dozens of servers, clients, and libraries that implement ActivityPub, the tracker helps to discovery which software can interoperate with inclusive handles.
If you know of ActivityPub software that isn’t on this list, or that doesn’t have its adoption tracked (question mark in the matrix), please add an issue or open a PR in the ActivityPub Webfinger task force repository.
@evanprodromou @jdlh I'm glad to say that the `webfinger` and `activitypub-webfinger` NodeJS libraries now support globally inclusive handles.

https://www.npmjs.com/package/activitypub-webfinger@evanprodromou @jdlh there are already a few other projects on the list already. I'm excited by these developments!

@evanprodromou @jdlh OK, I also got the activitypub.bot codebase (tags.pub and groups.pub too) to support it. The new version is 0.53.1, and the relevant ticket is here:
Support for non-ASCII Webfinger handles · Issue #282 · evanp/activitypub-bot
We need to confirm the following functionality: Receive: Can local users receive activities from a remote account with a non-ASCII handle? Send: Can local users send activities to a remote account with a non-ASCII handle? Link: Are non-A...
GitHub (github.com)
I'm going to go after onepage.pub next; it's a completely different codebase.

@evanprodromou@socialwebfoundation.org you should be able to add NodeBB to that list with
across the board. -
@julian @evanprodromou @swf I mean, yeah, I *should* be able to. Have you tested it?

@evan@cosocial.ca indeed I have <img class="not-responsive emoji" src="/emoji/ap/smile/activitypub.space" title="
" /> the issue's come up a bunch but when @edent@mastodon.social ran a public test, his internationalized handle was accepted ok.It's confirmed in code (all paths run through this regex):
const webfingerRegex = /^(@|acct:)?[\p{L}\p{N}\p{M}_.-]+@.+$/u;There were two places that could be cause for concern:
-
My Activity Intents implementation (@benpate@mastodon.social) uses a naive regular expression that only accepts ASCII, but this is not webfinger and is a bug I can fix to use the proper regular expression.
-
Requests to NodeBB requesting the unicode form of a domain will not match, because NodeBB expects punycode. This is compliant with the RFC. Likely browsers will natively translate unicode to punycode over the wire, but uncertain here.
Both of those are relatively minor, so broadly, NodeBB checks all the boxes.

@julian Awesome! Would you mind making a PR?
I added some implementation notes after implementing this, because there are some really hairy parts. The ASCII punctuation really kicked my butt, as well as the double-encoding of % characters:

I deployed a server with these handles. I hope they get linkified!
UPDATE: They did not! 0 for 35.
