Description
2.2.1. Detecting Word Boundaries: the word-boundary-detection property
A virtual word boundary is similar to the presence of the ZERO WIDTH SPACE (U+200B) character: it introduces a soft wrap opportunity and is affected by the word-boundary-expansion property. Its presence has no effect on text shaping, nor on word-spacing. However, inserting virtual word boundaries must have no effect on the underlying content, and must not affect the content of a plain text copy & paste operation.
The i18n WG thinks the text should probably also say that the virtual word boundary is invisible to justification algorithms (just like ZWSP), ie. add justification to the list after "Its presence has no effect on...".
