Do you use a screen reader? If so, which one, and what does it say when it encounters
25BC? When I have the MacOS default reader read
F107 in a browser it just doesn’t say anything for either, which would suggest to me that they’re equivalent to a screen reader. However, it also seems to ignore the
aria-hidden attribute, so maybe it’s not the best screen reader to test with.
Removing or replacing all font-based icons on the site would be a big effort, so big that we’d probably want to roll it into a wider accessibility overhaul, but that’s a long ways down the road. However, I think we could make incremental changes for icons where there is a clear unicode equivalent character, like ▼, , or , assuming it actually makes a difference to users of screen readers (FWIW, the only one of those characters the MacOS reader pronounced was ).
