The underline text generator adds a Unicode combining low line character (U+0332) after each character, creating an underline effect. This works in any Unicode-compatible app, even in plain text fields where HTML underline isn't available.

Use underlined Unicode text to add emphasis in Twitter posts, Instagram bios, Facebook comments, Discord servers, and other platforms. The underline is created with Unicode combining characters, so it doesn't require any special formatting support from the platform.

All processing happens in your browser — your text is never stored or transmitted.

Frequently Asked Questions

How does Unicode underline work?▾
The tool inserts a Unicode combining low line character (U+0332) after each character. When rendered, this combining character draws a line below the preceding character, creating an underline effect without HTML or CSS.
Where can I use underlined Unicode text?▾
Underlined Unicode text works on Twitter, Facebook, Instagram, Discord, WhatsApp, Telegram, YouTube comments, and any platform that renders Unicode. It's especially useful where HTML underline formatting isn't available.
Why does the underline appear broken or uneven?▾
Some fonts and platforms render combining characters differently, which can make the underline appear slightly uneven between characters. This is a limitation of Unicode combining characters, not the tool itself.
Is this the same as HTML underline?▾
No. HTML underline (the u tag) is a formatting instruction that only works in HTML contexts. Unicode underline uses combining characters that are part of the text itself, so it works in plain text fields too.
