Unicode 18.0.0

What does a zero-width joiner do?

A format character participating in context-sensitive shaping and some emoji sequences. Code points: U+200D. It does not ensure an emoji sequence or ligature will render as one glyph. No fallback is suggested. Font coverage, shaping, and application acceptance were not tested, so those results are unknown.
