There may also still be the occasional font embedded by Calibre import from docx where Book Check doesn't like the filename.
I only actually embed the fonts in a docx if the file is getting processed on another PC, or being emailed to someone. Uploads are all epub2, pdf and one place also dual mobi. I only use docx now for LO Writer export (extra save as) to Calibre import. The odt format doesn't 100% work with Calibre.
