Underline text generator
Underline adds a low line beneath each character. It is the most familiar way to mark a word as important without changing its shape at all.
Like the other combining styles it applies to whatever you type — letters, digits, punctuation, non-Latin scripts — which makes it one of the few options that works on any text.

Frequently asked questions
Does Underline work with non-Latin alphabets?
Yes. Underline adds marks or spacing around whatever you type instead of swapping in look-alike letters, so Korean, Japanese, Cyrillic and emoji all keep working. That makes it one of the few styles that is safe for multilingual bios.
Can I paste Underline text into Instagram?
Yes. These are ordinary Unicode characters, not a font file, so Instagram, TikTok, Discord, X and most other apps accept them in bios, display names and captions. Nothing is installed and nothing expires.
Some letters show up as empty boxes (□).
A box means the device rendering your text has no glyph for that character — the text itself is fine. Older Android builds and some in-app browsers are the usual culprits. Preview your text in the app you are pasting into before you save it, and fall back to a simpler style if it breaks.
