How to use Double Underline Text

Type your text, and the tool adds a Unicode double-underline combining character beneath every letter for strong emphasis.

Frequently asked questions

How does double underline work?

The tool appends the Unicode combining double low line (U+0333) beneath each letter and number, creating a double underline that travels with the text.

Is this the same as HTML underline?

No. This uses Unicode combining marks that work in plain text like social media and messages, where HTML underline tags do not apply.

Does it work everywhere?

Most modern platforms render combining marks correctly, though a few older systems may show the underline slightly offset.
