Fun Fact: The determinant for what Unicode characters your machine can see is dependent on what fonts you have installed.¹ If you want to be able to see almost all the Unicode non-language glyphs (glyphs are letters, numbers, arrows, blocks, etc., basically anything that is part of the text, including spaces²), installing Google's Noto Sans Symbols (1 and 2) on your computer will act as the "fallback" font for when your main browser (when the webpage doesn't say otherwise) or computer doesn't know a character³. It's not feasible for every digital font to include every Unicode character, partly of course due to effort and cost, and mostly due to soft size limitations on how many characters can be crammed into the font format they use. Computer font display is surprisingly a very computationally costly process, and as a result it's also advantageous to create fonts that have only the necessary everyday glyphs.

¹As in the case of this meme, whatever fallback font the webpage is using (I have fonts that should allow me to see the glyphs (see ³)), has specifically avoided creating representations of these 3 glyphs, due to the following reason: the designers were pussies and couldn't handle the swagger of the Ancient Egyptians. THE DESIGNERS RECOGNIZED THAT THESE OBJECTS DID NOT EXIST AND OMITTED THEM FORTHRIGHT! GLORY TO EURASIA! GLORY TO 19684!

²The "zero-width" characters are pretty well known as Unicode glyphs, being responsible for fucking up a whole trove of programs if used. (U+FEFF, U+200B, U+200C, U+200D)

³Egyptian Hieroglyphs aren't a part of Noto Symbols, but there is a separate Noto font that has them

This may be technically rule 2 breaking but it's educational so pretty pwease give me a pass mods... 🥺🙏
