I have a couple of ebooks that I'd like to have in the form of kepubs to benefit of the display engine. They are Japanese books and the epub rendering engine seems to ignore the right to left instruction, so one has to turn pages from left to right, which in the case of Japanese books is very awkward. The kepub engine seems to work fine, as I've confirmed in adding the right to left instruction in a random English book, and loading it both as a .epub and as a .kepub.epub (no conversion, just a change of extension), the first one turned in the "usual" direction while the second turned from right to left.

Now, my problem is I'd like to do the same for those Japanese epubs I have, but it doesn't work. If I convert them using the plugin it results in a really smaller file, which once loaded in the kobo can't be opened, there's a message saying that there's something wrong with the file. The same happens if I just change the extension to .kepub.epub. Now I don't know where the problem comes from: are these books not compliant to standards, or does the kobo have trouble with Japanese formatting, or is it the plugin ? As you can see, I'm beaten right now...

Turns out I was wrong. One of the epub I was trying to use actually works if I use the .kepub.epub extension without converting first, but when the book launches the display is blank. If I scroll until the screen is fully refreshed, all seems to work, although everything's pretty slow. Could it be because this book doesn't contain chapter, it's just one big block of text? Anyway, if I convert using the conversion plugin first, I can only read the first page, after which nothing is displayed. Not sure why that happens but using calibre's included reader causes the same issue.

Update: I've chaptered the half working good, and it's now a perfectly working book, if I use the .kepub.epub renaming without conversion. So I guess the other books have formatting problems, I'll check that. Anyway, sorry for the intrusion since I could find a solution which isn't even related to the main topic...
