About Unicode bold

It's not formatting, it's letters

Each bold character is a separate Unicode codepoint from the Mathematical Alphanumeric Symbols block. The boldness travels with the text wherever you paste it, no formatting required.

Use it sparingly

Screen readers can stumble on Unicode bold. Use it for emphasis on a word or two, not whole posts. A bio with 1 to 2 bold phrases reads great. An entirely bold caption reads like spam.

Where it works

Instagram, LinkedIn, X, Facebook, Threads, TikTok, Pinterest, Bluesky, Mastodon. Anywhere that accepts Unicode in posts. WhatsApp, Telegram, and Discord have native bold but this still works there too.
