[j.p.s]

When a (first?) occurrance of an X-ray entity with 2 or more words has a newline between 2 of the words in the text of the book the entity label has a newline between those words in the generated X-ray file. This can be seen in the attached example.png

WordDumb might also make two entiies, one with a newline embedded in the label and one without. It is also possible to workaround this by making an entry in the worddumb-custom-x-ray.json file for the book with an alias that has "\n" in place of the space as can be seen in workaround.txt

Also attached is NewlineBug.tar.gz which has an azw3 of the public domain book, a worddumb-custom-x-ray.json for both cases, a temporary worddumb.json plugin configuration file, the 2 generated XRAY.*.asc files, and a script to generate the XRAY files and tsv dumps of the entity and entity_description tables for both cases.
