It will remove many emoji from comments as well, although not all of them. Not sure what the criteria is for that, either.


Not just emoji either e.g. the box-drawing characters (https://en.wikipedia.org/wiki/Box-drawing_character) also get stripped.

OTOH domino or mahjong tiles (🁓, 🀕), playing cards (🃅) or musical symbols (𝅗𝅥) are allowed. So are arrows (↸) including supplementals (⤪), number forms (ↈ), superscripts and subscripts (⁴₂), "miscelllaneous technical" (⎋, ⏱) or geometric symbols (◉), however misc symbols (https://en.wikipedia.org/wiki/Miscellaneous_Symbols) is a no.

So yeah, pretty arbitrary. I guess pg likes playing domino but hates chess.

Also funny note: we have access to musical symbols but not notes, because the notes are in the misc. symbols block. Unless you want to use byzantine (𝀶) or ancient greek (𝈙) musical notation then it's OK.


On FF on (older) Android I get the symbols here:

But not the others, they're just get boxes; except the boxes which are missing completely (ironic).

IIRC, we had access to UTF font formats (using bold, outlaid, double, open, etc., letter forms) and to Zalgo, Z̸̠̽a̷͍̟̱͔͛͘̚ĺ̸͎̌̄̌g̷͓͈̗̓͌̏̉o̴̢̺̹̕ ?


> But not the others, they're just get boxes; except the boxes which are missing completely (ironic).

That's a different issue, the glyphs are missing from your machine's fonts rather than HN stripping them.


Yeah, I wanted to use U+266A once and it didn't let me, but random emoji gets through: https://news.ycombinator.com/item?id=23028433


Box-drawing characters are allowed. I made a comment[1] a while ago that used them to make a table. Unless they're only allowed in monospace blocks?

Interesting! It looks like the box drawing are allowed but the block elements are not, and I just used the box elements in my test assuming they'd behave the same!

Sorry for having been misleading.


That’s a shame, because I could see legit and serious reasons why someone would want emoji in comments. For instance, what if someone was trying to illustrate a point by “drawing” a diagram of a network, using different emoji to represent different types of nodes.


As someone who despises emojis, I am more than happy that they are removed. There are other ways we could show the hypothetical example.


Agree. It's almost as if using vocabulary is wrong. I've been watching how our conversations deteriorate by gratuitous use of emoji. It seems that some seem to think that emoji can cut through all language barriers, because they're universally understood. Unfortunately, the effect I see is newspeak to the detriment of all, as we lose the nuances of language itself, and indeed we become more 'visual only' in our language.

Unicode penis?

𓀐𓂸 edit: yeah hieroglyphics are allowed apparently


Get thee behind me, Zalgo!


On some platforms, the emoji is so small that is difficult to determine what it is, let alone what it's supposed to represent.


One that comes to mind is the "thrangrycat" vulnerability. I say "thrangrycat" but the researches insist on calling it . I've taken liberty of shortening the excerpt to the more reasonable reasons, as the answer got more nonsensical as it went on.

>How do you describe the meaning of this vulnerability name?

>We chose to communicate through a visual representation of symbols, rather than “words.” Naming vulnerabilities using emoji sequences instead of other pronounceable natural languages have several advantages. First, emoji sequences are universally understood across nearly all natural languages. Choosing instead of a name rooted in any one language ensures that the technical contents of our research can be discussed democratically and without latent cultural or linguistic bias...

Edit: and HackerNews has indeed stripped the emojis used to name this vulnerability.
