Should I use bold Unicode in page headings?

No. Crawlers treat these as symbols, so real headings should stay plain text with actual markup.

Serif or sans-serif bold?

Sans-serif matches most app interfaces; serif looks more editorial and stands out more against a UI font.

Do numbers get bolded too?

Yes, this block includes bold digits, so prices and dates convert cleanly.

Bold

These characters live in Unicode's mathematical alphanumeric symbols block, encoded so that a bold variable stays distinct from a regular one in formulas. Search engines and screen readers see them as mathematical symbols rather than ordinary letters, so use them for accent rather than for headlines that need to be indexed. Within a bio or a post, they are the cleanest way to add emphasis.

Where people use it

Emphasising a line in a LinkedIn or Facebook post
Highlighting a call to action in a bio
Product names in marketplace listings
Section headers in plain-text documents
