Using the bold generator

Type on the left. Style starts on Bold and also offers Bold italic, plus Bold cursive and Bold gothic if you want something further from ordinary type.

Swap the boxes to get plain letters back, whichever of the styles the text arrived in.

Bold is the one with numbers

Most of the styles in this Unicode block are letters only. Bold is different. It carries a full set of digits, because a bold number means something specific in mathematics, and they sit at U+1D7CE onwards while the bold capitals start back at U+1D400.

That makes it the practical choice for the things people actually want emphasized in a bio or a listing. Prices, dates, times, a phone number. Cursive and gothic would leave every one of those flat.

Double-struck and monospace carry digits as well, if you want something less shouty.

Where you shouldn't use it

Anywhere with a real bold. Discord, Reddit, WhatsApp and anything Markdown-shaped will make **this** bold properly, and properly means a screen reader still hears the word.

These characters are mathematical variables. Unless a search folds them back to plain letters, a shop name written this way matches nothing anyone types.

Use it in a box with no formatting and no search depending on it.

Why a bold A is its own character

In print, bold is a second cut of a typeface and the letter underneath is the same letter. In mathematics it isn't. A bold 𝐯 is a vector where a plain v is a scalar, and the two can sit in one equation meaning different things.

Unicode had to let plain text carry that distinction, so it encoded each variant separately in 2001. Everything on this page is a side effect of that decision, and none of it was aimed at anyone's bio.

Related conversions

Italic is the same block, one style along. Cursive and gothic are the decorative ends of it, both without digits.

For emphasis that shrinks rather than thickens, small text drops everything to small capitals.

Questions

Why does bold text work in my Instagram bio when there's no bold button?

Because it isn't formatting. Each bold letter is its own character that Instagram stores like any other, so there's nothing for it to strip.

Does bold text include numbers?

Yes, all 10 of them. Double-struck and monospace carry digits too, while cursive, gothic and italic have none at all.

Should I use this on Discord?

No. Discord has real bold with double asterisks, and that version reads correctly to a screen reader. Keep this for places with no formatting at all.

Will search find my bold text?

Not reliably. Unicode maps each one back to a plain letter, but a search only matches them if it applies that mapping.
