I see that you close the ticket saying it doesn't happens to you.
I was not able to reply to the ticket, so I write here.
I have tried again also with default converter settings, but I got a lot of words with a dash in the middle where there was the hyphenation in the src pdf.
Not "giardino" anymore ... a lot of others.
As you can see in the link:
I used the same file I sent to you with default converters settings.
Do you succeded in converting without these iusses using some different settings ?
