Underline Text Generator — Copy & Paste
Add underlines to your text using Unicode combining characters.
Unicode Underline Text
Most social media platforms don't support underline formatting, but Unicode combining characters solve that. Our underline text generator adds combining underline characters (U+0332 for single, U+0333 for double) after each letter, creating text that appears underlined everywhere — even where formatting isn't supported.
We offer multiple underline-related styles: single underline, double underline, overline, combined strikethrough + underline, and overline + underline. Each uses different Unicode combining characters to achieve a distinct visual effect.
Underline vs Strikethrough
Both underline and strikethrough use the same combining character technique. Underline adds marks below the text baseline, while strikethrough adds them through the middle. You can even combine both for a dramatic crossed-and-underlined effect using our "Strike + Underline" style.

Frequently Asked Questions
Why does the underline look broken on some platforms?
Unicode combining underline characters attach to individual letters rather than forming a continuous line. This can create slight gaps between characters depending on the font used by the platform. The effect is most noticeable on platforms using monospace fonts.
Can I underline text on Instagram?
Yes. Instagram doesn't have a built-in underline feature, but Unicode combining underline characters work in Instagram bios, captions, and comments. The underline renders correctly for all viewers.
