The template {{zwnj}} inserts the code ‌ literally, which produces a ZERO WIDTH NON-JOINER in the rendered wiki-page.

This is a convenience template for the zero-width space character, Error using {{unichar}}: Input "200C" is not a hexadecimal value..
It is completely invisible in display, but has the effect of acting as a breaking point at an otherwise non-breaking situation, e.g. within continuous text inside a word that otherwise would possibly break.
