#[tantek]While this is (primarily) a social media problem (posts, profile bios), I feel this is worth capturing somewhere for indieweb too, perhaps as an advantage?
#[tantek]On your personal site, you can use actual fonts with CSS, rather than have to work around silo limitations with a bad for accessibility hack of using Unicode characters for a different “font” look
#[KevinMarks]it's a screen reader problem. All of those characters have a defined fallback letter that screen readers could use instead of reciting the unicode name string
#petermolnarwhich is why those should overwrite the corresponding unicode characters instead of using the "free for all" area of unicode
#[KevinMarks]but they do have well defined plaintext fallbacks, it's a choice by screen readers to read them stupidly.
#sknebelthe decision when the fallback is appropriate and when using it is destroying context is probably not so easy though. although I guess a bunch of the text use could be caught be heuristics with low error risk
#[KevinMarks]even if it is a mathematical equation, saying MATHEMATICAL ITALIC SMALL E EQUALS SIGN MATHEMATICAL ITALIC SMALL M MATHEMATICAL ITALIC SMALL C SUPERSCRIPT TWO is deeply unhelpful

#[tantek]presumably if that's what screenreaders universally do, it's harmful *today* to use such symbols instead of actual letters
