How it works
Each character is replaced with its full-width form, originally designed so Latin letters line up with Chinese, Japanese, and Korean characters. Spaces become the full-width ideographic space.
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.
