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…

>These unicode characters feel like they were given to us from an alien species or something. I worked at a large media company that had lots of differing icon sets in play across different media. These icons were in SVG and they had been optimized pretty intensely. In some cases due to a bug in one of the optimizing tools some types of bezier curves got weird, so instead of say the round headed person with their han…

The person who appears to have done the work of collecting this character (and others) for submission into the Unicode process back in 1997[0] (Barbara Beeton) has actually responded to the StackExchange question[1].

Unfortunately even she is not aware of what the symbol is actually for.

High school physics and math as a major. I could scan you my scripts and papers if you're interested.....no won't. ;-D But maybe "commonly used" was maybe the wrong term. More appropriately: "sometimes" or "by some".

Where in the world? I’ve never used it despite similar background. Perhaps regional?

I remember the days of people beginning to abuse ftp sites, all us admins shutting down our writable ftp upload folders, and thinking, "this is why we can't have nice things." It was the beginning of the end of the early, friendly internet.

Wearz were very nice things.

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…

Some of the glyphs you mention are combinatorial code points. i.e. they are multibyte characters combined to a single character. So you add a gender modifier and skin color modifier to change the appearance. You don't add multiple code points. It's your device rendering these 2-3 byte character sets as single icons/emojis.

> So you add a gender modifier and skin color modifier to change the appearance. You don't add multiple code points.

FWIW that's true for the skin colors (there are 5 fitzpatrick scale modifiers, U+1F3FB to U+1F3FF), but it's not true for the gender: the basic gendered characters (e.g. U+1F468 "MAN", U+1F469 "WOMAN") were part of the original set "merged" from japanese emoji so the gender-neutral equivalent (e.g. U+1F9D1 "ADULT") was added as a separate codepoints.

Dislosure: I'm not directly from the fields of the Sciences Of Angles And Ambiguously Crossing Lines nor I've every seen or used this symbol before. However to me it's, pretty evidently, supposed to be a "no right angle" symbol. (A) It's in the math section, (B) it's with angles, (C) the thunderbolt ↯ is commonly used for "not" or more specifically for dis-proof in this area and (D) at least by my 30 s internet searc…

I submit to you that it's clearly not a thunderbolt but an arrow indicating changing directions; that being overlaid on top of a pair of axes is obviously useful in the study of non-Euclidean geometry to indicate the use of wibbly-wobbly dimensions.

Usually called Little Free Libraries in the US. (The name is a little weird, because regular libraries are also free...)

FWIW "Little Free Library" is a trademark and its owners have been aggressive in its defense. I don't know what folks should use as a generic name.

It seems bizarre to me that someone could trademark such a straightforwardly descriptive name.

> 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.

I do not get it. Did you have to shut it down? Does not make sense to complain that someone uploaded stuff to a public unprotected writable storage. Wouldn't securing it with a set of credentials suffice?

I think, you don't get the full grasp of "early, friendly internet". Very few people do today. In my bubble - programming, for example, young people can't even imagine that there were times when you could focus on _things_ instead of writing layers of security code around them.

It’s like how when I was a kid, nobody in our neighborhood locked their doors at night. There was no need. Until there was.
