Mathematical Bold Capital G

7/996

In Word, enter 1D406 and press Alt+X to produce 𝐆. In a formula, it can mark a G that has a different role from plain G. As of 2026, it also works as a bold-looking letter in plain-text styling, though it is a separate character rather than a formatting command.

Text symbol

What 𝐆 means

In Word, enter 1D406 and press Alt+X. If other hexadecimal characters touch the code, select just 1D406 first; otherwise Word may convert the wrong sequence.

What does bold G mean in math?

It can stand for a different variable than plain G. There is no fixed quantity hidden in the letter; the writer defines it in the equation. Bold is semantic here: it separates one mathematical symbol from another, not just a stretch of heavier ink.

In 1999, scientific-publishing contributors Barbara Beeton and Murray Sargent proposed a wider mathematical alphabet so digital formulas could preserve distinctions already used in print. Earlier character sets had only a few standalone, letter-shaped math symbols; this encoding expanded that partial set.

Why does 𝐆 turn into plain G?

Compatibility normalization can fold it into plain G. NFKC, a Unicode text-cleanup form that ignores certain character distinctions, maps 𝐆 to ordinary Latin capital G. That can help software compare text loosely or check identifiers, but it erases the bold distinction. Keep the original character when an equation depends on it.

Mathematical in formulas; decorative in plain-text styling.

In an equation, bold can distinguish variables; treating it as mere emphasis loses that distinction.

Why does 𝐆 show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
