I don't think this is a very good comparison -- the difference you're missing is that if you embed inline images or custom links into a HN comment, they degrade gracefully into URLs that anyone can use.

  [click me](https://google.com)
  <a href="https://google.com">click me</a>
  <img src="thiscatdoesnotexist.com" alt="this cat does not exist" />
In HTML, if a browser doesn't support images, they also degrade gracefully into alt tags, which work with screen readers -- images can even be styled with CSS to avoid document reflows. This is common practice on platforms like email, where remote images will often be blocked.

I'm not saying avoid emoji, I'm saying avoid encoding them into a format that literally stops rendering or turns into an undecipherable mess the moment it's not fully supported -- especially since there are other encoding formats we could use that would be just as good as Unicode and that wouldn't have any of its downsides. In general, we should try to build escalators, not elevators.

Agreed, but what is the better escalator in this case?

IMO for most text-fields and markdown interfaces it's a shortcode.

  :smile: :calculator: :pikachu_brandishing_ketchup:
The only big downside to shortcodes are that they're more than one character long, but there's no good way I can think of to have screenreader-accessible emoji that doesn't contain a multiple-character description anyway.

Shortcodes will get passed properly through 99.9% of existing text processors without any problems, so it's a really safe format to store things in.

I think the conversion to pictorial form should only happen at the display layer. If you're writing HTML, I advocate for using an SVG with a title attribute. Unicode emoji are already SVGs, so the only thing that changes is you don't bundle your emoji into a font.

Even native applications understand how to automatically highlight things like urls with the `https://` `http://` format, so my personal vote is we just use shortcodes the same way we use URLs.
