Out of 27 PDFs containing ISBNs, the plugin has detected correctly the ISBN in 9 of them, so I wouldn't say "it doesn't work with PDFs"!

What I see (been a long time since I did anything with ISBN (13)
IIRC ASCII characters only
A single space is valid but not when a dash is used
A minus sign dash is valid, but not emdash or double dash
No space when used with dash is valid. And no mix
What is Language code 85? There are 3 books with that one.
