I.e. alt text for zalgo text, text that uses Unicode letter variants, emoji-heavy text, etc.
I'm aware of the technique of applying `aria-hidden="true"` to the problem text, then applying "screenreader" CSS styles to the accessible version, but in the interest of making my content portable I'd like a way that didn't rely on CSS from my own website.
@esbe This looks like the most recent, reasonable suggestion I can turn up: https://lists.w3.org/Archives/Public/public-aria/2018Feb/0028.html
@alx interesting, `role="img"` hadn't crossed my mind
@esbe Yeah, it feels like a little bit of a stretch, but viewed as 'img' meaning "information presented in a graphical, screen-reader-unfriendly manner" it's more acceptable than the alternatives I've seen.
