What is underline text?

Underline text uses Unicode combining low line characters (U+0332) placed under each letter, creating an underline effect like U̲n̲d̲e̲r̲l̲i̲n̲e̲. Since HTML underlines don't work in social media posts, this Unicode method is the only way to add underlines to plain text.

Why use it in your posts?

Underline signals importance and draws attention in a different way to bold. LinkedIn creators use underline to highlight key terms, definitions, and headings in long-form posts — particularly effective because it is rarely used, making it stand out.
