FAQ

Will screen readers read this correctly?+

Some will, many won't. These characters live outside the standard letter ranges, so accessibility tools may pronounce them oddly or skip them. Avoid using them for anything that needs to be read aloud.

Why doesn't every style support digits?+

Unicode doesn't define italic-only digits. Where digits exist (bold, sans, mono), they're included.
