How it works
These aren’t really fonts. Each letter is swapped for a look-alike Unicode character, such as the “mathematical script” letters used for cursive. Because they’re real characters, the style survives copy and paste into apps that don’t allow formatting.
Things to know
Screen readers may read these characters oddly or skip them, and search engines don’t treat them as ordinary words. Use them for a word or two of emphasis, not for whole posts, usernames you want people to search for, or anything that needs to be accessible.
