Created a document titled When Anabaptists Get Angry; The Wrath of God in a Process - Anabaptist Perspective.docx (content from this article online; I'd edited it to make all the footnotes real footnotes).
Tried to build it into a PB but got the following errors:
[Error] Error while building book: Error while discovering resource.
[Error] Exception: LDLS4.Panels.PersonalBookBuilderPanel.PersonalBookBuilderException: Error while discovering resource.
Renamed the file When Anabaptists Get Angry - The Wrath of God in a Process-Anabaptist Perspective.docx to get rid of the semi-colon (which is a legit character in filenames in Windows, BTW; the title of the article had a colon in it, but that's not a legit character for filenames in Windows, so I'd changed it to a ; ). Rebuilt and it worked.
EXPECT: Any allowable filename in Windows should be handled by the PB builder. Shouldn't have had to rename it.
