The number and unit are joined by U+00A0 in this example.
No-break space
The no-break space U+00A0 keeps adjacent text together, such as a number and its unit. It can look just like an ordinary space.
NO-BREAK SPACE
Invisible character — the marker is not part of copied text.

3 code pointsMeaning and context
The no-break space U+00A0 keeps adjacent text together, such as a number and its unit. It can look just like an ordinary space.
How to use it
Use it deliberately where a number and its label should stay together. Inspect the stored code point when text refuses to wrap or a comparison unexpectedly fails.
Examples
Compare the boundary
A B versus A B
The first gap is no-break space; the second is ordinary U+0020.
