How it works
A combining stroke character is placed after each letter: U+0336 for a long stroke, U+0335 for a short one, U+0338 for a slash, and U+0334 for a wavy line. Because they’re characters rather than formatting, the effect survives copy and paste.
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.
