I can't see the problem with an unofficial encyclopedia
if fans would buy that, they will happily buy an official encyclopedia from the author, even if they already own the unofficial version.

unless JKR has shown manuscripts of her unfinished encyclopedia to someone, how could the unofficial encyclopedia contain that many entries verbatim?
.......unless those passages are quotes from the HP series, in which case, the official encyclopedia won't contain much that is new to HP fans
