推荐答案

这是不可能知道这一点，取决于字体的度量和它的呈现方式。不间断的空间通常以与同一字体中的常规空间相同的宽度呈现，它只是建议浏览器不要在那一点换行或折叠空间。

It's not possible to know this accurately, because it will depend on the font's metrics and the way it's rendered. A non-breaking space is usually rendered with the same width as a regular space in the same font, it just suggests to the browser not to wrap at that point or collapse the space.

您不应该依赖于以特定方式呈现的字体，以便在页面上排列设计元素。以适当的单位指定距离，在不适合的情况下不要使用不间断的空格。

You should never rely on fonts rendering a particular way in order to line up design elements on the page. Specify distances in units that are appropriate, and don't use non-breaking spaces in situations for which they aren't suitable.

您可以从值开始，例如 0.4em 。但是如果你绝对必须完全匹配一个不间断的空间的宽度，你正在使用一个不间断的空间。

You could start with a value of, say, around 0.4em. But if you absolutely have to exactly match the width of a non-breaking space, you are using a non-breaking space incorrectly.
