Just for anyone having this same issue, i.e. when converting epub to kepub via calibre, the
page-count on a kobo/tolino is doubled and the first actual page is somewhere in the middle -
I just found a solution for the issue (at least, for the book I had it with):
When I edit the epub-version with calibre (right click -> edit book), the text-documents had a space in their name, e.g. "Book Title_split_001.html".
The content.opf (under Miscellaneous) had them as
Code:
<item ... href="Text/Book Title_split_001.html" ... />
while the toc.ncx had each navPoint as
Code:
<content src="Text/Book%20Title_split_001.html"/>
The entry in content.opf is the incorrect one - an href is a URI reference, so a space has to be
encoded as %20. Calibre passes both spellings through to the kepub unchanged, so the conversion
itself is fine; the reader seems to treat the two spellings as two separate files, which would
explain the doubled count and the content starting halfway through.
To fix this, I:
- Renamed all the text files and replaced the whitespace with _
- Adjusted the entries in content.opf to Book_Title_split_001.html
- Did the same for the entries in toc.ncx
Then I re-converted, and from then on it worked just fine.
