[wff]

Hi guys,
I am new here, and I hope my issue have not been already solved elsewhere (even if it would be nice concerning my problem ;-)
Well, I have a Kobo Aura H2O. I manage my Ebooks with Calibre and KTE. And I need your help with an EPub->KePub conversion. My concern is about one single book of my Calibre Library.
I converted my ePub as usual, but when I wanted to read it with Kobo, I was surprised to notice that there was "display" problems: mostly spaces missing or excessive spaces. It doesn’t prevent me to read the book, but it catches my eyes and disturb me, what is not very comfortable...
I tried some things to fix that before calling for help: convert again to Kepub, change kepub output, change font, ... I sent the original ePub to kobo, and there was no problem of display and spaces and other stuff. But I need Kepub, because I like to see the real page number even when I change font size or margins. I even tried to convert EPUB to EPUB and then KEPUB again.
So I came to the conclusion I have a problem with conversion.
Here are some files to show my issue:
- screenshots of what the book is supposed to be [epub on Marvin iOS]
- ss of what I get [kepub on Kobo]
- ss of the epub file in Calibre Ebook Edit.
- Extract of the first two chapters of the book (including copyrights).
Thanks for your help,
Florent
