Might we run out of Unicode code points, like we (seem to) be running out of IPv4 addresses? As another comment mentions, once you add all these snowmen, with/without snow, male female and gender-neutral, in a few skin colour options (plus neutral)... it adds up. Plus, exponential growth once you consider family of snowmen (different number/genders/races of "parents", different number/gender/races of "children" and s…

> it adds up.

It really, really doesn't.

According to UTS #51, as of unicode 14 (and its ~140000 allocated codepoints) there are under 3500 codepoints classified as emoji.

And do keep in mind that #, or ®, are classified as emoji.

And incidentally, U+2654 "white chess king" (♔) was in unicode 1.0. The moral panic around emoji is really tiring, it's absolute, utter nonsense, every single time.

I remember back in the day we used to find publicly exposed Windows FTP servers, create new folders using some messed up unicode characters and upload pirated games and movies there to share with each other. The only way to open those directories was to specifically type the exact path in unicode, simply double clicking on the folder in filezilla or windows explorer resulted in a error. Sometimes the admins themselve…

You too, huh? This was my first foray into the "dark" side of the Internet as a kid, pre-Web, hanging out with pirates on IRC and get "hired" to go around the early 'Net and fuck up people's upload folders by creating hidden directories we could load with our group's warez. ^H^H^H^H

AMS = American Mathematical Society last i subscribed. How the heck would someone surveying mathematicians not have found that?

In a linked post Barbara Beeton says not. She collated these characters while working for the AMS so she should know.

Wake up, first thing that pops into my head, "I should check HN" (normally it's imgur, yeah bad habits). Number one post is the Linking Sigil. Neat. If you know, you know. As for how a chaos magick symbol concocted in the 21st century ended up in a 1994 font spec, clearly discordians used the power of fnord to retcon it.

Im sorry to be a party pooper but though Linking Sigil is also mentioned in the article but that's not what the article is refering/asking about.

Hmm, the article links to the Linking Sigil at the bottom, in the links section.

But the rest of the article is concerned with how mysterious the symbol is, and how no one knows where it came from.

A clue: anyone can register a symbol for a surprisingly small fee.

A question: why would the sigil be mentioned in an addendum but not in the article proper?

Anyway, it's pretty obvious that GP had a premonition this morning, with a pay off.

These icons were in SVG and they had been optimized pretty intensely.

There are some kanji scripts that has no record of existing usage in the JIS character encoding which was also incorporated to the Unicode. It's called "ghost character" in Japanese. https://ja.wikipedia.org/wiki/%E5%B9%BD%E9%9C%8A%E6%96%87%E5...

I feel bad for the font designers who have to put all these inane characters in, have to draw them and hint them, and they have no purpose except they have to be there or someone will complain.

And still no external link character, ridiculous.

Hm, now that you mention it, I always thought of the external link symbol as being a box with an arrow coming from inside it and protruding out of the upper right hand corner, but I don't see that symbol anywhere in Unicode, and I'm not sure why I have that association.

There is the U+1F517 link symbol but I'm not sure that's communicating the same thing.

> the thunderbolt ↯ is commonly used for "not" or more specifically for dis-proof in this area and I don't think it's that common. At least, I don't recall seeing it ever. Maybe it's used in non-English mathematics? Wikipedia mentions it's also used in electrolysis so maybe this new one is related to that somehow?

It's used in german mathematics education (secondary level), either to mark a contradiction in a proof or more generally to mark an erroneous statement.

Also in Dutch universities to mark a contradiction, especially in a proof by contradiction.

So Unicode has all these mysterious characters... but I would bet that it's still true that many people on the planet speaking common languages can't even type their name... This post is from 2015, and I'd love to know if unicode has added better support for non-English languages since then. https://modelviewculture.com/pieces/i-can-text-you-a-pile-of... Based on https://en.wikipedia.org/wiki/Bengali_(Unicode_block)…

The article present it like it purely due to western-centrism these characters does not have distinct code points in Unicode. In reality the issue is much more subtle - a discussion whether a certain glyph is a ligature of two characters or its own distinct character.
