Did you find a way to address the issues presented while keeping #IconFonts?
Basically:
When our friends with #Dyslexia overrides your fonts, font icons turn into black boxes since the font they're using doesn't have support for those Unicode code blocks.
When screenreaders, or voice assistance, reads a site with icon fonts, they read the icon fonts really weird.
For No.2, a site with properly marked aria labels, or marked as hidden for assistive tech, is the solution I can think of.
However, for No.1, I can't think of a way since once the browser forces the user font, all fonts on the site will rely on the user's custom font.
The only other way I can think of is to provide an option to switch the site's font right from the website, so they don't have to override the site's font.
I've been geeking out with Apple's #assistive features. Specifically voice control and switch control. face tracking. Anyone out there using these features? And if so I'd love to hear about how you're using them and best approaches, pitfalls etc.
