How it works

A combining underline character (U+0332, or U+0333 for double) is added after each letter. Some fonts and apps join them into a continuous line, others show short separate dashes under each letter.

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.

How it looks in different apps

Combining characters attach to the letter before them, and each font decides how to draw them. On iPhone and Mac the underline is usually continuous; on some Android and Windows fonts it appears as small separate dashes. Spaces get an underline too, so the line runs across the whole phrase. Preview your text in the app you’re posting to before relying on it.

Frequently asked questions

Why does underlined text count as twice as long?

Each letter is followed by an invisible combining character, so the text has about twice as many characters. Keep that in mind where there is a character limit, such as a bio.

What is the difference between single and double underline?

Single uses U+0332 (combining low line) and double uses U+0333 (combining double low line).

Can I remove the underline later?

Paste the text into Find and replace, turn on “Regular expression”, and replace [\u0332\u0333] with nothing.
