> 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?

I believe I have seen it used as a symbol which indicates the discharge of an assumption, but never for "not".

I've thought that it would be cool to have a Wiki with an entry for each character, describing what it is, and its history. Although that wouldn't help for mystery characters like this one, there are a lot of characters with stories behind them.

Eventually Unicode will think, "Hey, maybe bold, italic and underline aren't just decorative, but required formatting which conveys emphasis, and other information that needs to be contained within the text itself!"

Or, maybe not and we'll continue to lose formatting every time we copy and paste and be forced to use plain text for the rest of our lives. Also, we can color our emojis now, but that WARNING text can't be in red. Because colors don't matter?

Which ever person decided basic formatting shouldn't be in the spec was wrong and we lose important details every day because of it.

These unicode characters feel like they were given to us from an alien species or something. How did it we end up with so many characters of unknown origin? I had no idea what it meant or was used for, thus assigned it a “descriptive name” when collating the symbols for the STIX project. (I still have no idea, nor can supply an example of the symbol in use.) […] it is the case that ISO 9573-13 existed long before eit…

Something similar exists in JIS called 幽霊文字 (ghost characters), which refers to kanji of mysterious origin with no real-world usage that somehow made its way into the JIS character set. After some investigation, most of them turns out to be mistranscriptions of kanji from old historical materials.

"wah-rez"

Wait what? It’s pronounced like the city in Mexico?

I've heard a lot of people pronounce it like that, but I'm pretty sure that's not correct. It's clearly the English word "wares"[1] with the S replaced with a Z, similar to "hackz" and "cheatz", which were also common in that era. I think the "wah-rez" pronunciation came from people seeing the l33tspeak and not recognizing the original word behind it.

[1] A synonym for "goods" or "products". See https://www.merriam-webster.com/dictionary/wares

The successful bitcoin sign proposal [1] explicitly deals with such a criticism: > Will Unicode be flooded with symbols for many crypto-currencies? > Most other crypto-currencies have learned from the difficulty that a non-Unicode symbol causes for Bitcoin, and use a symbol already in Unicode. For instance, Dogecoin uses Đ, Ethereum uses Ξ, Litecoin uses Ł, Namecoin uses ℕ, Peercoin uses Ᵽ and Primecoin uses Ψ. Some,…

It seem to me that this is something best handled with tag characters, like ¤XBT + (U+E007F) = ₿ (where the letters are from the tag block, U+E00xx). This mirrors one of the two systems for rendering national flags[0], just with a different starting codepoint, and can easily accommodate all the ISO 4217 currency codes and common unofficial extensions. If a system doesn't know how to render a particular glyph it can j…

That sounds interesting, but modern currency symbols are already fast-tracked anyway---they almost always get assigned in the next version of Unicode---and more than one currency symbols for given ISO 4217 code can exist so I don't think it would work.

Sometimes people should be able to do nice things without it getting abused, no? In The Netherlands, in the nicer neighborhoods we have something called a ‘buurtbieb’ aka a ‘neighborhood libraries’, which is a weatherproof cabinet where people can put surplus books that other people in the neighborhood can borrow. Of course you could take all the books or use the cabinet to store candy, but why would you?

We have these throughout many neighborhoods in my city in central Florida, USA. We’re a college town so I just assumed it was somehow connected to that. Neat that it’s an international thing!

Here in Brazil we have those on bus stops.

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.

Fortunately there are only a handful of such cases. But unfortunately there are tons of commonly used CJKV ideographs; typical Chinese or Japanese fonts are of course not expected to have all Chinese characters (there are almost 100,000 of them while OpenType fonts can only have 65K glyphs), but they are expected to have thousands of commonly used characters.

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…

There is no reason to believe the current rate (about ~35,000 over the period 2010--2020) to change rapidly, so we are probably safe for this century. You should be aware that emoji gender and skin color is encoded in character sequences and modifiers rather than atomic characters, exactly in order to avoid that exponential growth. And in the unlikely case that Unicode gets so many characters somehow, you can always…

> emoji gender and skin color is encoded in character sequences

A good tool to see this broken down is https://unicode-x-ray.vercel.app/?t=%E2%9C%8C%F0%9F%8F%BC%F0... (edit: fixed url to use percent encoded emoji)

That doesn't jive with the history in TFA — the Unicode name and location was inferred from the symbol itself without knowledge of its meaning.

I don't see the contradiction. The only thing they used from the name is the "right angle" aspect. Given their argument is this is a composition of thunderbolt + X, for some X (and derived from their prior knowledge of thunderbolt's compositional meaning), deciphering the image as "thunderbolt + right angle" is trivial and consistent with the naming origin in TFA.
