Portable combining underline
Underline Text Generator
This underline text generator adds a line beneath every character using a Unicode combining underline mark, so the underlined text copies and pastes into places that have no formatting toolbar — bios, captions, LinkedIn posts, chat messages, and display names. The mark is U+0332 (COMBINING LOW LINE), and it travels with the text as a real character rather than a style setting.
Because the underline is a combining mark stacked onto each letter, it works anywhere the base letters do, and it survives a copy-paste that would strip rich-text formatting. Type below and copy the underlined result; preview it where you'll use it, since a handful of apps normalise combining marks away.

Copy and paste in four steps.
Type or paste the text you want underlined into the box below.
Check the underline result — a combining underline is added to each character as you type.
Copy the underlined output with one tap.
Paste it into a bio, caption, message, or document; if the line disappears, the app has stripped combining marks and there's no workaround on that surface.
Built for real places you paste text.
Social bios & captions
An underlined word or phrase for emphasis where the app gives you no formatting controls.
Chats & display names
Underlined names and message accents in apps that pass Unicode through untouched.
Notes & docs
A quick underline in plain-text fields and lightweight editors.
LinkedIn posts
LinkedIn's post composer has no underline (or bold) button, so a pasted Unicode underline is the only way to underline a phrase there. Keep it to a few words — see the link caveat in the FAQ.
Type it natively instead.
Microsoft Word
Select the text, then press Ctrl+U (Windows) or ⌘+U (Mac). Ctrl+Shift+D gives a double underline in Word for Windows.
Google Docs
Select the text, then press Ctrl+U (Windows) or ⌘+U (Mac).
Discord
Wrap the text in two underscores on each side — __like this__ — and Discord's own markdown underlines it, no Unicode needed.
HTML
Wrap the words in a <u> tag, or use CSS text-decoration: underline. Both vanish the moment the text is copied into a plain-text field.
Frequently asked questions
01How does an underline text generator work without a formatting button?+
It attaches a Unicode combining low line to each character. The underline is part of the text itself, so it pastes into plain-text fields that have no underline option.
02How do I copy and paste underlined text?+
Type into the generator above, tap Copy, and paste into the field you need. The underline comes along with the letters.
03Why does my underline sometimes not show up?+
Some platforms strip or normalise combining marks for consistency or safety. When that happens the base letters stay but the line is removed, and there's no fix on that specific surface.
04Is this the same as typing underscores between letters?+
No. Underscores between characters sit on the baseline. This tool places a continuous underline beneath each character, closer to a true underline.
05Does underlined Unicode text work in Word or Google Docs?+
It pastes and displays, but for documents you'll keep editing, the app's own underline formatting is cleaner because it's a text attribute rather than stacked marks.
06How do I underline text on LinkedIn or Instagram?+
Neither app has an underline button, so type your phrase into the generator above, copy the result, and paste it into the post, caption, bio, or comment. The underline is part of the characters, so the app has nothing to strip.
07Will underlined text look like a link?+
To some readers, yes — an underline is the classic signal for a clickable link, which is one reason social apps don't offer it. Underline a short phrase for emphasis, and never underline something readers might try to tap.
08Does underlined text use up more of my character limit?+
Yes. Every underlined letter is two code points — the letter plus U+0332 — so a 20-letter phrase costs about 40 characters toward a limit like Instagram's 150-character bio.
09Can I make a double underline?+
Unicode has a combining double low line (U+0333), but this generator uses the single U+0332 line because it renders most consistently across apps. In Word you can get a native double underline with Ctrl+Shift+D.
10Is underlined Unicode text searchable?+
Not reliably. The combining marks make the word a different character string, so platform search and screen readers can miss it or read it awkwardly — keep keywords and key information in plain text.
