Still no seahorse

JohnKemeny | 8 hours ago

If the seahorse emoji is introduced, we will have to train new foundation models. The costs connected to the introduction of the seahorse emoji will be in the billions.

zarzavat | 8 hours ago

You're absolutely right—the seahorse emoji was added in Unicode version 19.0.0 after OpenAI purchased the Unicode Consortium and converted it to a for-profit corporation.

simondotau | 6 hours ago

The seahorse being, of course, among the first commercial Unicode characters that require a subscription to use.

I would be more interested if they are ever going to cancel HAN unification. Looking at their "Factors for Exclusion" list it could be summarized by "we made some mistakes in past but are sticking to it" :D

Han Unification was effectively "fixed" by Ideographic Variation Sequences, so no.

account42 | 6 hours ago

You mean theoretically. Effectively, nothing is fixed yet.

lifthrasiir | 6 hours ago

IVD works, theoretically and practically (recent versions of OpenType have an explicit support for them). It's not their fault that Japanese vendors have been not very quick to adopt them.

account42 | 5 hours ago

If a Japanese and Taiwanese person type things with their keyboards and end up with the same bytes for different logical characters then no things do not work practically for any practical definition of "practically".

lifthrasiir | 5 hours ago

Your argument is absurd because people don't see code---they see glyphs, and using the same code for slightly different glyphs is a non-issue when they are not interchanged. (And when they are interchanged, both would see glyphs "correct" to them anyway.) Japaneses are sensitive to Han unification only because they recognize more glyph variations (Z-variants) than what Unicode originally could, and IVS is exactly a tool for ensuring exact glyphs assuming cooperative vendors. Not to mention that Han unification was already quite weakened by source separation principles in the first place.

Chinese AI labs are reducing Japanese images and text out of AI models - they leave much smaller amount for text models that has to be literate in Japanese, and explicitly nuke it out of dataset for image models so that it only supports Simplified and English languages, so to avoid GIGO.

I mean, making or help making sovereign AI models is nowhere near responsibilities of Unicode, but Han Unification and sort of a default-enforced IVD support is literally adding small but non-zero amount of fuel to cultural division and xenophobia perpetuate in East Asia. I doubt blaming users would work here.

Other great additions:

- Left and Right parenthesis with middle ring [1]

- A wiggly exclamation mark expressing mirth or laughter [1] (edit: and something I completely missed: the inverted version can express sarcasm)

- Cuneiform numerals, including lots of arranged dots that might be useful in other contexts [2]

- New variations of "measured angle" and "sector" [3]

- A transparent cube and a white cube [4]

Also a couple new combining marks

And for anyone who wants to see what the reference images for the new emojis look like:

I need a table emoji because then I could combine it with a horse emoji. This would be "Pferd Tisch" (Horse Table) in German which sounds similar to "Fertig" which translates to "done". Yes I want it only for that dumb joke.

Does anyone know why a monarch butterfly was added, when there is already a butterfly emoji?

pentamassiv | 6 hours ago

Sadly it looks like it will be a dead monarch butterfly

The internet needs a "tin foil hat" emoji, but two proposals have been rejected :(

Emoji proposals and status: https://unicode.org/emoji/emoji-proposals-status.html

turblety | 8 hours ago

Did they give a reason why it was declined? Was it some bureaucratic "form not filled in correct" thing, or are they actually against the concept of it?

lifthrasiir | 8 hours ago

Vendors-have-no-capacity-to-handle-more-than-handful-number-of-emojis-per-each-release thing.

To elaborate: it should be plain obvious that not every Emoji proposal can be accepted even though all of them are correctly filed, as there would be too many Emojis there then. So there has to be some threshold, and that threshold is mostly stipulated by vendors' willingness to process new Emoji characters for designing fonts and updating softwares in time.

zyx321 | 8 hours ago

That list only includes suggestions that were seriously considered and voted on.

Since it's a vote, there is no single official 'reason' for rejection. If I had to guess: it would be confusing to anyone who didn't grow up with American TV shows.

pwdisswordfishq | 8 hours ago

Eh, it's not like there are hundreds of emojises pretty much exclusively tied to Japanese culture.

maxbond | 7 hours ago

They were grandfathered in, not voted on. Or rather there was a vote that resulted in adopting the character sets developed by Japanese telecoms en masse.

Ekaros | 5 hours ago

Weirdly this is in line with Unicode in general. Widespread (and not even widespread) historic use in say print results in characters getting included.

mananaysiempre | 6 hours ago

> emojises

I don’t protest the coinage here (goodness knows my native language did worse things to English words), but I can’t stop saying it in Gollum’s voice.

wodenokoto | 7 hours ago

Generally Unicode is for encoding all existing encodings/writing.

So you generally can’t add something because it would be cool or fun or useful, but only because it is currently in use and cannot be encoded by Unicode.

chordbug | 6 hours ago

If this were entirely true, we'd never see new emoji added, and yet we do.

goodmythical | 2 hours ago

That's not at all the case. Unicode began as a standard for making things like string(':)') in to a single character.

Consider all of the languages it supports. Consider: ﷽ (which isn't an emoji, but the point stands) which is an entire sentence. It was already in use in certain places and unicode decided they wanted to support it, so now they do. Previously, one would have to type out the entire sentence in the original characters, but now it is a single unicode, just like u+263a () used to be alt+1 (). The emoji was already in use long before unicode existed, and in seeing it in common use, they decided to support it.

brikym | 7 hours ago

Seems like a conspiracy. Also it's so silly that pistol turned into water pistol.

account42 | 6 hours ago

The entire notion that emoticons should be limited to what a committee approves (which is then mangled by corporate PR even further) is ridiculous. Just retvrn to images.

brikym | 6 hours ago

This. But more work is needed. I tried a bunch of Discord alternatives like Matrix but very few have a fun experience with things custom emoji images that really make a chat server feel like a home.

uxellodunum | an hour ago

There are clients on Matrix that support custom emojii, such as Sable and Commet. Neither are absolutely perfect, but I know people who daily-drive one of the other (or both, which is where I'm at depending on the device).

For the most part, now that Matrix is merging those Matrix 2.0 specs finally, and the 2.0 features are already out in the wild with excellent results, it has a really good base, and as expected we've started to see clients build more into the average-consumer space to pose as alternatives to both niche and mainstream audiences such as Discord, Whatsapp, etc - Which it just wasn't/isn't able to do on Matrix 1.x (legacy).

poulpy123 | 8 hours ago

looking at the changes it makes me wonder:

- is there an usable font the cover all unicode ?

- if not is there really a point to include everything possible in unicode ?

- how many space is remaining for new alphabet and smileys ?

- how do they handle changes in scripts, for example if new proto-cuneiform or seal script symbols are discovered ?

pveierland | 8 hours ago

The Noto fonts have great coverage: https://notofonts.github.io/overview/

infinita740 | 7 hours ago

Pretty cool vizualisation.

There is also GNU unifont [1] "The original intent of Unifont was to offer a simple font format with wide Unicode coverage to render something meaningful for each Unicode code point"

wongarsu | 8 hours ago

> if not is there really a point to include everything possible in unicode ?

Needing to load three fonts to show a single document that mixes vastly different character sets is still infinitely better than not being able to have those different characters in the same .txt or .md file at all

> how many space is remaining for new alphabet and smileys ?

Unicode can encode about 1100k code points, and about 800k of those are currently unassigned and available for future scripts or characters

tecleandor | 8 hours ago

> how do they handle changes in scripts, for example if new proto-cuneiform or seal script symbols are discovered

They get added in the next Unicode revision.

In Unicode you have "blocks" [0] that are often bigger than the number of characters in a script, language or function. There are usually also space for new blocks between unrelated blocks.

For example, in the case of cuneiform, it was introduced in Unicode 5.0, and there have been revisions in 7.0 and 8.0 [1]

As an example of having not-exactly-a-character as Unicode "characters", it is rather rare that musical symbols are embedded in running texts (which is a primary litmus test for encoding), but musical symbols are typically rendered with existing font technology so there are needs for standardized "character" codes, as SMuFL [1] does. In fact Unicode 18 will get tons of musical symbols that have been in SMuFL for a long time but not yet in Unicode [2].

No toki pona?

pwdisswordfishq | 8 hours ago

Does it need any additional code points?

florianist | 4 hours ago

The Toki Pona script (aka sitelen pona) needs some codepoints for its ideograms. While Toki Pona is not in Unicode, tokiponists have mostly agreed to use the U+F19xx range in the Private Use Area-A. Most fonts rendering sitelen pona uses that. But using PUA is problematic (no character properties, a lot of restrictions on the web, and constant clashes with other fonts [such as the "nerdfonts" for example]).

Hey ChatGPT show me a seahorse emoji.

sourcegrift | 7 hours ago

Personally the whole emoji thing is an unmitigated disaster. I'm okay with smileys and gestures but everything else is pointless

vintermann | 7 hours ago

I'm okay with smileys, but Unicode wasn't the right standard to deal with it. Unicode maybe wasn't the right standard to deal with anything.

At least nothing is wiggling. Of those Unicode points which are graphical, at least all of them can still be printed on paper and won't require a screen. I wonder how long that invariant lasts.

account42 | 6 hours ago

It's classic scope creep resulting in unmanageable bloat.
Personally I think the whole emoji thing is a triumph of Unicode. Being able to convey more subtext through emoji makes communication so much easier especially across language boundaries.
I enjoy putting emojis in folder names on my computer for easier visual identification.

Also, in passwords on websites to keep developers on their toes.

The password thing is hilarious but the former breaks some of my Unix tools

Google/Apple needed it to fill the moat for Japanese phone market - for Google it was because Japanese carriers were stripping emoji from outgoing emails, and for Apple it was because iPhone as a real phone and not an Internet-connected pocket PC with voice call had to support the SoftBank emoji set.

And yeah, :slack-style-emoji-notation: is superior. It was just a historical necessity for Google/Apple.
