Conversion Error - pdf to epub

There's a bug in the new function to remove hyphens - I suspect it's because your document has actual parenthesized words with hyphens in the middle on a line break. Neglected to consider that particular case in the new code. Can you open a bug with your file to verify for certain and use as a test?

I've created a test case to reproduce this, so a fix should be in the next release, but it would still be good to submit a bug with your pdf just in case I'm mis-interpreting the error.
