Latest change breaks chapters for some books

[Diegus83]

I tried the latest commit that removes the dependency for eyeD3 and it breaks the chapters function for this particular book: Ball Lightning by Cixin Liu I think it might have something to do with the special characters in the names of some chapters (@, / ).

I tried other three books with regular characters (a-z, :, -) in the names and it worked fine.

Thanks for the report.

Spent more time trying to debug this than the actual porting over to mutagen from eyed3. I've decided to revert back to using eyed3 until I have more time to look at this.

Closing this since the revert back to eyed3 has fixed the issue.
