I'm responsible for this character being supported in Iosevka, JetBrains Mono, 3270, and Cozette, looks like. For arguments I wanted to stick to mathematical convention like f(x) without looking like a regular variable. While the lowercase 𝕩 (subject role) is more common, uppercase makes it a function and is useful in functional programming. More visibility for the character is helpful if it means wider font support, although the real sticking point has been lousy UTF-16 handling on Windows. Like most emoji, these characters need to be represented as a surrogate pair in UTF-16, and terminals in particular often don't handle it.<p><a href="https://mlochbaum.github.io/BQN/fonts.html" rel="nofollow noreferrer">https://mlochbaum.github.io/BQN/fonts.html</a><p><a href="https://mlochbaum.github.io/BQN/help/rightargument.html" rel="nofollow noreferrer">https://mlochbaum.github.io/BQN/help/rightargument.html</a>
This is for math.<p>In Latex, you get these symbols with \mathbb{}. They are most commonly used to represent to represent number sets, like the set of all integers Z (from the German), set of all natural numbers N, set of complex numbers C, set of all real numbers R, rationals Q (for “quotient”), set of quaternions H (named after Hamilton), or an unknown set F (for “field”). This explains why many of the letters in this series exist in the basic multilingual plane—because R is very commonly used, but A is not. You can find ℝ in the basic multilingual plane at U+211D.<p>I don’t know why people are interested in the X symbol. It’s just there to complete the alphabet. There are many other ranges like this used for writing mathematical formulas, like the range of bold letters, fraktur, script, etc.
Interesting comment on the Register (by Jedit):<p><i>However, it's also exactly identical to Unicode character 1D54F - because that's all it is. And if you examine the full "X" logo in detail, you'll notice that the scratch in the background doesn't reach the X because all the logo creator did was put U+1D54F in a black square and slap it onto the backdrop. It's the epitome of laziness.</i><p><a href="https://forums.theregister.com/forum/all/2023/07/24/twitter_brand/#c_4700793" rel="nofollow noreferrer">https://forums.theregister.com/forum/all/2023/07/24/twitter_...</a>

These tweets by @SawyerMerritt seem to have been the "inspiration" for X's logo:<p><a href="https://twitter.com/SawyerMerritt/status/1683150433806692352" rel="nofollow noreferrer">https://twitter.com/SawyerMerritt/status/1683150433806692352</a><p><i>Correction to my previous reply: @ajtourville designed the thicker X logo below for our (now discontinued) @OfficialXPod.

And this Alex guy is taking the credit for designing it?
It's actually time for someone to adopt this character [1] at the gold level ($5,000), which is only allowed for the single entity and doesn't expire---so that X.com doesn't have a chance to sponsor the character at the same level.<p>[1] <a href="https://home.unicode.org/adopt-a-character/about-adopt-a-character/" rel="nofollow noreferrer">https://home.unicode.org/adopt-a-character/about-adopt-a-cha...</a>
Interestingly, [w3.org Math Double struck] shows example glyph rendering with swapped double stroke stem ("//" + "\" instead of "\\" + "/").<p>Been looking what the "opf" in the `&Xopf;` HTML entity name of this kind of character means, and apparently it is "Open Face".<p>It is referenced at [wikipedia Blackboard bold] that mentions that "𝕏 Occasionally used to denote an arbitrary metric space.

It makes typesetting easer, pretty genius really! /s<p>We're going to see a trend of companies using Unicode characters for their logo now aren't we?...

I see on the page there are also unicode symbols for roman numerals IX, X, and XI.
I can see an argument for having a separate character for roman numeral X as opposed to just using a capital X like a normal person would, but where do they get off calling IX and XI numerals? They are two-character sequences, and adding characters for the combinations sounds like all pain and no gain.

Can’t find it now, but originally it was reported that Elon got the logo from someone who replied to his tweet and that it was the lid logo for someone’s unsuccessful podcast.
Anyone have any knowledge of how the new CEO and Elons relationship is regarding the business? I'd be curious how the conversation goes with her about this kinda stuff.

Wow, this probably changes everything we thought we knew about this company, the product and its CEO.<p>No, seriously, does he think no one notices that the new X logo still hides the same old Twitter crap?

Musk can seem to do no right atm, I see a lot of hate out there with this name change and planned product expansion but I can’t quite understand why.
He’s taking an underperforming social network and trying to make it work. It might prove fatal, but it would have died a slow boring death in its old form. Perhaps its just that people don’t like his personality, which shouldn’t come into it.<p>Fwiw even prior to his defunding moderation it felt like one of the meanest places on the internet, I don’t see much of a change.
