Right angles have a small box near the vertex which denotes it is a right angle [0]. This symbol doesn't have that box, so I don't think it's a right angle.

> 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 the first symbol referenced for symbols used in proof by contradiction to show contradiction [0]. I know that's not exactly "not" or "disproof" but I think that might be what the poster was getting at.

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-w…

It's not a synonym for "goods", because only one type of thing was ever "wares"; software. It's just for dividing up the sections of your piracy BBS into, like "filez" (files, multi-kilobyte textfiles full of instructions on how to make bombs etc), "imagez", "warez", etc.

Anyway, by 1990, in the piracy circles I distantly associated with, it was quite common to pronounce it like "juarez". Sort of semi-ironically, like, it's obviously the wrong pronunciation, but nonetheless everyone uses that pronunciation on purpose. So, what could be more correct than "the thing everyone does"?

Of course, pronunciation only happens in meatspace (or at least it did back before MP3s and before YouTube and so on), and of course I'm talking about clusters of teenagers separated by thousands of km. We had "meetupz" or "meetz" in my city, which is how I know how "everyone" pronounced it... but it's certainly possible that in most cities/whatever there was some other pronunciation rule.

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.

I like this idea. It would serve as a place to put a well-sourced answer to the question about this character, and the talk section could be used to discuss further investigation into the topic, or when new uses inevitably arise.

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…

I remember convincing friend to build unicode pokedex extension that collected all the unicode symbol he was exposed to via cansual web browsing. Never followed up but I think it'd be neat, or something along the lines of rare unicode browser bingo.

> ⋚ U+22DA LESS-THAN EQUAL TO OR GREATER-THAN > ⋛ U+22DB GREATER-THAN EQUAL TO OR LESS-THAN These are very interesting. What would be the use case for these?

This blew my mind:

"Related terms

I generally (perhaps naively) think that going forward knowledge loss won't be much of an issue compared to our history. Surely the archeologists of the future won't have to wonder what some tool from our times was used for or what some symbol we currently use means… They will have Wikipedia and archive.org and whatnot! But that fantasy is not compatible with reality where we are already unable to find out what is th…

Electronics become unusuable quickly, though. We can find stone tablets and clay pottery, but 10k years from now will they be able to find hard drives and extract useful data? Seems like it can easily go in the opposite direction

This is probably an edge case, but I work in lab software that uses chemical symbols and having sub and super characters saves lots of headaches. I can just store "CO₂" in a database, query it, and display it back as a simple string, or display values in scientific notation like 1,3×10³, without having to use any formatting. But to be honest I'm not sure what the parent comment wants to see added because at the momen…

Upper-case subscripts are missing, for one: I'm not allowed to talk about the normal force F_N in plain text email. Superscript and subscript Greek letters would also be nice to have, eg in context of relativity.

Why not Devanagari then? This Europe-centric point of view bother me.

Also, I've seen a lot of different symbols as subscripts in mathematical and physical articles, like squares, triangles, arrows, etc.
