Use it in messages and captions; emoji artwork and interpretation differ between platforms.
U+1F171 U+FE0F identifies this exact B button (blood type) form; copying the character preserves its Unicode identity, while its appearance depends on the font or emoji renderer.
B button (blood type) can act as a visual label for its named subject in a caption or list. It is not a standardized replacement for a written label in technical or safety information. B button (blood type) is a sequence of 2 Unicode code points, not a single character. Keep every part when copying it: removing a joiner, selector or component can change the result.
