Why use them?

This evening, when I was writing a post about an ImageMagick command that I’ve learnt, I used the unit “pixel” to describe the dimensions of an image.1 In a measurement, the quantity and the unit should be separated by a non-breaking space for the sake of readability.2

To illustrate the effect of a non-breaking space, I’ll use some screenshots.

How to use them?

Unlike pandoc markdown, one can’t use \ for a non-breaking space.3

The external URL of this linklog has a link to a Wikipedia page which is cited in footnote 2. From the table in the section “Keyboard entry methods”, I can directly insert the non-breaking space character using Linux compose key.4
