As someone who has developed several #ActivityPub software implementations (Fedify, Hollo, BotKit, and Hackers' Pub), I believe one of the most frustrating features to implement in the #fediverse is #custom_emoji.

The challenges are numerous:

First, there's no standardization. ActivityPub specifications don't define how custom emoji should work, leading to inconsistent implementations across different servers like Mastodon and Misskey.

Rendering is particularly problematic. Emojis must display properly across different contexts (in text, as reactions, in emoji pickers) while maintaining quality at various sizes. Animated emojis add another layer of complexity.

Perhaps most concerning is the poor #accessibility. Most implementations simply use the emoji code (like :party_blob:) as the alt text, which provides no meaningful information to screen reader users (in particular, non-English speakers) about what the emoji actually depicts or means.

What really dampens my motivation to implement this feature is knowing I'm investing significant effort into something that ultimately creates accessibility barriers. It's disheartening to work hard on a feature that excludes part of the community.

@hongminhee let's make a new standard for adding metadata to emojos! I think there is enough motivation around this feature to get the various implementors to add new stuff to it!

@hongminhee sounds like there needs to be a better FEP written, one which encourages alt text for custom emojis?

@thisismissem@hachyderm.io Yeah, if it's standardized al text should be considered…

@liaizon@social.wake.st I appreciate the enthusiasm, but I personally don't have much motivation to standardize custom emoji. While I understand many people enjoy this feature, I'm not particularly fond of custom emoji functionality in general. My limited interest in the feature itself, combined with the significant accessibility issues it creates, makes it difficult for me to get excited about investing time in standardization efforts. Though I respect that others might feel differently!

@hongminhee I know there's a FEP for emoji reactions, but I don't think there's ever been one for custom emojis? https://codeberg.org/fediverse/fep/src/branch/main/fep/c0e0/fep-c0e0.md

@hongminhee I plan to write a FEP documenting existing implementations (it is needed to finalize my emoji reactions FEP).

Do you know implementations that provide alt text for custom emojis?

silverpill@mitra.social I personally didn't find integrating custom emoji to be difficult at all.

However NodeBB did already have custom emoji support (so it was fairly straightforward to add the outbound federation support), and as for inbound, the short code is defined in the payload and a simple regex replace handles it ok.

Sure, some emoji might look weird if they have different aspect ratios, but that's something outside the scope of what I'd want. All remote emoji are reduced down to a small square (or technically I think it's maybe max width and height of 1rem or similar), inline with the text and that honestly works with like 99% of the emoji I see.

That said an FEP would be nice so I'd be able to verify that my implementation checks all the boxes.

Another annoying thing about the current custom emoji spec in the fediverse: the type is just called Emoji instead of CustomEmoji. Such a small detail, but it creates unnecessary ambiguity between Unicode emojis and custom ones. I ran into this while implementing BotKit and had type name collisions with Emoji—had to use awkward namespacing to work around it. These little inconsistencies make implementation more tedious than it needs to be.

Listed requirements for the Emoji object.
I should probably describe the microsynax there as well, and how custom emojis are rendered.

@silverpill @julian @hongminhee you have listed "Image is a square" but is definitely not true for Misskey. And Mastodon renders Misskeys long emojos just fine.
Actually mastodon does fine with long emojos now too

@thisismissem@hachyderm.io You're right, I don't believe there's a specific FEP for custom emojis yet. If one were to be created, accessibility through proper alt text would definitely need to be a core requirement. The current state where emoji codes like :blob_wave: become the alt text creates significant barriers for screen reader users—especially for non-English speakers, who face an additional language barrier when trying to understand these codes. A proper standard should address how to provide meaningful descriptions that actually convey what the emoji represents in multiple languages.
