How to use

How do I underline text in Unicode?

Add the combining low line character (U+0332) after each letter. This tool inserts it automatically so the text shows underlined.

What is the special symbol for underline?

It is the Unicode combining low line, U+0332, placed under each character. It is not the keyboard underscore, which sits on its own.

Does Unicode underline work in WhatsApp and Instagram?

Yes. Both render the combining underline characters, so the text appears underlined in chats, bios, and captions.

Is this the same as the HTML underline tag?

No. HTML underline only works in web pages. Unicode underline works in any Unicode-capable text field.

Can I underline and bold text at the same time?

Yes. Convert to bold Unicode first, then apply underline combining characters on top.
