AB
The sample contains a no-break boundary between the letters.
Word joiner
The word joiner U+2060 discourages a line break without adding a visible gap. It differs from zero-width space, which allows a break opportunity.
WORD JOINER
Invisible character — the marker is not part of copied text.

The word joiner U+2060 discourages a line break without adding a visible gap. It differs from zero-width space, which allows a break opportunity.
How to use it
Use it only for an intentional no-break boundary. When diagnosing text layout, show its code point explicitly because the visible line may not reveal its presence.
