Description
The Highlighter and FastVectorHighlighter can be configured to delineate passages using a target character length, that is then typically adjusted for the word boundary. This would be a good option to add to the UnifiedHighlighter (UH) in it's own right, as well as for better back-wards compatibility to those using this highlighter.

Research direction
Start with the UnifiedHighlighter entry point and compare how Highlighter and FastVectorHighlighter configure passage delineation by target character length. Inspect the related highlighter tests, if present, and consider the work done when UnifiedHighlighter supports max-character passage sizing with word-boundary adjustment.
