The attached KFX file is a free book of a Japanese public domain novel published by Amazon.
When I convert it to EPUB with Calibre, I can see it correctly with the Calibre viewer. However, when I convert it to EPUB with "From KFX", there is a blank line between the paragraphs.
Some viewers show it correctly while others do not.
I think the margin setting in the CSS file is not optimal for vertical text.
Could you modify the KFX input plugin?
