Underlines made from combining marks
Each underlined letter is followed by a combining low line (U+0332), a mark that draws itself under the character before it. A double underline uses U+0333 and the wavy version uses a combining tilde below. The marks attach to the letters, so the underline travels with your text when you paste it.
Underline shortcuts
Word and Google Docs use Ctrl + U (Cmd + U on Mac). Discord uses two underscores on each side (__text__). Instagram, TikTok and X have no underline option, so copy it from here. Underlines can look like links, so use them for headings and emphasis rather than whole sentences.
See it before you paste it
Profiles, chats and video captions all show it a little differently.
