    It is a little known electrical engineering schematic symbol. It simply means a ground to neutral leg junction of a 3 phase circuit. The point where they come together. Where you might find this symbol is just before an earth ground symbol. It is discontinued now for the most part, but was used to denote a way to help with the radio noise a 3-phase circuit makes so as to not allow bleed over to shortwave radio, cb radio, uhf tv, ect. Now the noise is generally cancelled out with ferrite beads, shielding, and filters.

It's close but not exactly the same. Check it please and if it is the same let us know and where it is located on the schematic. I am curious as this was and as far as I know still is used to show where a ferrite beaded cord or cable was called for. I would not think this would be hardwired into a motherboard but I guess if there is a lot of rf shielding needed maybe so. That is why I am curious as to where it is on the schematic.

Ltd., entitled "List of mathematical characters" (1972), where the symbol was designated with the matrix serial number S16139. The whole AFII thing was a red herring.

    Decent video, there's one thing about Unicode I think is important to understand to understand why this wasn't just allowed to happen, but *had* to happen. The goal of Unicode was to replace *every* previously existing character encoding standard. That means a core rule of Unicode is that it must support "round-trip conversion" with every older standard. You must be able to convert a document in a previous standard into unicode, and then back again to the previous standard, and the final document must be unchanged. So for example "one dot leader" (․) might be in practice exactly the same as a period (.), but Unicode has to give them separate characters, because in XCCS (the Xerox Character Code Standard from 1980) they were separate characters, so if Unicode collapsed them both into period then converting an XCCS document containing one dot leaders to unicode and back would result in the one dot leaders being changed to periods. And if there was a risk that converting an XCCS document to Unicode might damage (alter) the document, then that might give people an incentive to keep around documents in XCCS, thus defeating the goal of Unicode to be the one and only world standard. This roundtrip rule is why, if an ISO standard ever contained a character simply by accident (like ⍼), Unicode is *not allowed* to correct that accident.
    The roundtrip conversion requirement is also part of why Unicode contains about twenty different characters for a space (at least one of which is completely redundant with another space character) and, in the Arabic Presentation Forms-A block, a prayer ("﷽" -- that is one character right there, codepoint 65021, it's called the Basmala and it's a blessing common in the Muslim world to open prayers or in some places legal documents).

    So, back in the day, we used to have terminals that printed characters out -- like a typewriter -- instead of a computer screen. -- You would connect to a mainframe, send it commands, and it would respond by printing characters out.
    A common trick, was to use backspace (which can't delete an already printed character), and just print a new letter over the top.
    So to underline something, you could print a "_" and a backspace, and then the letter "S", and that would give you an underlined S right there.
    This looks like two characters that may have been used in some ancient application, that they were probably porting to a modern system (that used screens instead of printers!) back in the mid 90s, and they wanted to make sure that future terminal applications would maintain compatibility with some crazy double printed character.

      Interesting unicode in your name ;) . For the original use of most ASCII characters, imagine that you were sending them to a printer, and you didn't send a new one until the previous one had been finished. Carriage return moved the print head (the "carriage") back to the starting point, but didn't move the paper. Line feed moved the paper, but not the carriage. Tab originally moved the carriage to a mechanical marker (the "tab"- this behavior was inherited from typewriters, where manually set tabs were used to make it easier to fill in forms with typewriters; this usage is why the tab key will sometimes move a cursor to the next GUI control), before being changed to fixed spacing. Other character encodings did similar things.

    Back in the 80's SPSS used this symbol to mean "unplottable negative value", like, for a scatterplot to see the correlation between time to complete the survey and number of correct answers, it's okay if the scatterplot shows a negative *correlation* of data points from the upper left to the lower right inside the plot, but this data representation assumes 1) no one reversed time and completed their survey in -2 minutes, or 2) got 14 questions wrong on a 10-question form. So this was (and may still be) statistical shorthand for "data points appearing in supposedly impossible negative territory."

    It can be a symbol for large models, like LLM. Large models come from large data sets that are then converted into much smaller files, but can then be used to generate content.

    The thing about The Unicode Consortium is that they do not care what do the symbols mean.

And if symbol exists and someone had used it, they add it in.

    • @gwalla
      @gwalla 5 หลายเดือนก่อน +1

      That's not quite true. They just assign names and properties to character codes, but the actual appearance is left up to fonts. The code charts do include pictures, but they aren't definitive. Things like the box drawing characters and block elements have names like UPPER RIGHT BLOCK DIAGONAL LOWER MIDDLE TO LOWER RIGHT (Unicode names are officially in ALLCAPS for some reason) because their shape *is* their meaning.
      This actually causes some problems with emoji, which are generally chosen based on their graphical looks, but may look somewhat different to a recipient, leading to confusion. This is especially common with the facial expression emoticons: one example is the notorious Samsung Pervert Grimace.

      There's a whole lot of "block" characters in Unicode, as well as in the proprietary character sets used by various vintage computers. On the old computers they came from, they were used to draw pictures in text mode. It was a way you could make primitive pictures on a computer that didn't have a graphics mode. Or maybe you didn't want to enter graphics mode because it was lower resolution than text mode and you just wanted to draw a distinctive frame around your text box and graphics mode would make any text you draw ugly and blocky.
      So, it isn't a specific part of a larger picture, it's a building block you can use many different ways. You might put a bunch of UPPER RIGHT BLOCK DIAGONAL LOWER MIDDLE TO LOWER RIGHT in a row to make a saw blade 🭓🭓🭓🭓🭓🭓🭓🭓. Or you might use one of them to make a smooth transition from a bold horizontal line made up of UPPER HALF BLOCK, to an even thicker horizontal line made of FULL BLOCK ▀▀▀▀▀🭓█████. (No clue whether either of these will look nice, my Windows 10 doesn't have 🭓 in a font Chrome cares to use on TH-cam so I just get a rectangle with an X in it. Edit: Neither does my Android phone. I'm beginning to think this character isn't actually implemented on anything and is more of a placeholder to be used by a one-off font to be packed in with an emulator for whatever retro computer it was on.)

The ordinary symbol for lightning is very similar with a right angle and a zigzag with an arrowhead. The double zigzag with a right angle in a different orientation means heavy thunderstorm associated with a sandstorm. It is so similar it is almost surely a weather symbol that has been copied wrong, or is no longer in use.

    In the Japanese encoding system JIS X 0208, there are a few kanji encoded that are not found in any kanji dictionary. These are commonly known as “ghost characters” (yuurei moji 幽霊文字).
    The standard acknowledged the sources for these characters, but later people were unable to find these characters in the original sources. Later it was found that the encoded forms were wrong, and the forms that were supposed to be taken, were not encoded. Despite this, one character remains truly elusive, 55-27 彁 (U+5F41), its sources were not acknowledged and no results were found after extensive research. The character 彁 has since then become an internet phenomenon.

      The wrong characters are still there, because once a character is encoded, you can’t remove it. The correct characters were added later to different JIS code pages.
      The most famous of such characters is 54-12 妛,which was a mistake for 𡚴。The source, when preparing the script for print, stuck two pieces of paper together for the 山 and 女 parts, but the gap in the paper created a mark in the print, and this was mistakenly spread as a vertical line in the middle. The right form 𡚴 was encoded in JIS X 0213.
      Likewise, 52-63 壥 is believed to be a mistake of 㕓, but the correct form is still not in JIS X 0213.
      For a more extreme case, 61-73 汢 was encoded for a place name, but the source character was wrong, and it should have had 冫instead of 氵。This character is still not even in Unicode. In 2002, the place that used this character officially changed their name to the form with 汢 for convenience.

    I could see it as a way to represent a third axis (Z axis) since having a third line identical to X and Y would just look like a weird sideways y or something - in other words, it would be easily confused.
    And since trying to add extra detail like dashes or entire included symbols would make the symbol unnecessarily complex, having an arrow to signify “the third axis” was the most simplistic possible solution.
    Basically just Axis X and Y as the angle, arrow designating axis Z.
    Though I’ve got no clue what it is for sure so don’t quote me here.

    I think this symbol should come to represent "Dord" which is the accidental word invented as a symbol for density that was added to the dictionary when someone mistook "D or d" for a word because because someone didn't leave enough space between the "or" and the lower and uppercase D's.
    Spaces are important. I once saw a hand written sign that was meant to say "Pen is broken" but because there was no space between "pen" and "is" It led me to ask the only male there how he had done it, and why he felt we all needed to know it was broken.
    He was very confused until I pointed out the sign to him.

    I've used that symbol decades ago meaning that the vertical axis in a graph is NOT continuous nor proportional. Example: a graph of X:workers in a Y:monthly-salary. In this graph, there will be nothing between $0 and, let's say, $1,000, so instead of drawing a huge empty bottom, you hack the start to 1,000 instead of 0; plus you hack the Y-axis again between $5,000 and $20,000 because that's the top of the "normal workers" and the minimum of the "CEOs and friends", thus the Y-axis is NOT a complete-range nor continuous and the top range of paid people is distorted to look closer to the workers.
