🔘

单选按钮

A radio button user interface element, used in form fields with two or more choices. Differs from a checkbox, in that only one response can be selected.

This emoji generally shows the on/enabled state for the radio button, with a smaller circle inside a larger outer circle.

Note: this emoji is not supported in Twitter / X names, to minimize confusion with a verified checkmark. Learn more here.

单选按钮 在 2010 被批准为 统一码6.0 的一部分,并在 2015 被添加到 Emoji 1.0 中.
