The Illusion of LinkedIn Formatting: Why Your Bold Text is Actually a Trick

Ever wondered how people write in bold or italics on LinkedIn? It’s not a real feature—it’s a Unicode trick that messes with screen readers. Here is how it works and why you should use it sparingly.

The Unicode Illusion

Formatting on LinkedIn is a trick, not a feature. Once you see how it works, you can’t unsee it.

LinkedIn doesn’t actually support bold or italic text. What you see in those posts isn’t formatting at all—it’s Unicode. Specific character ranges (mathematical alphanumeric symbols, if you want to be precise) happen to look like styled Latin letters. Your browser renders them; LinkedIn just passes them through.

Which means every “bold” headline you’ve ever scrolled past is technically a different letter. The B in a bold post isn’t a B. It’s 𝐁. A separate codepoint that screen readers, by the way, often can’t read properly… something worth knowing before you go wild with it.

Why I Built a Free LinkedIn Formatter

I got asked often enough how I do it that I built a small tool for it. You paste markdown (italic, bold), and it spits out the unicode-styled version, ready to drop into a LinkedIn post. No login, no tracking, no upsell. It does one thing.

A Quiet Indictment of the Platform

The slightly uncomfortable part: LinkedIn could add real formatting tomorrow. They’ve had over twenty years to do it. The fact that an entire cottage industry of “LinkedIn formatters” exists is a quiet indictment of the platform, not a clever workaround by its users.

Use It Sparingly

Use it sparingly. A bold sentence in a sea of plain text catches the eye. A bold sentence in a sea of bold sentences just looks like noise.
