Hello,
I am the coordinator of the group "Ebooks libres et gratuits" -
http://www.ebooksgratuits.com. My English is very bad. I made tests with Calibre for conversion epub of our ebooks; I speak about it here, in french:

The result of a ebook makes with Calibre:
http://www.ebooksgratuits.com/temp/e...tees_html.epub
I used a file HTML, obtained starting from a Word file and improved (a few) with a text editor. The result is rather good, Calibre is a good software. But there are some small problems which could be perhaps corrected:
* In French, one needs a nonbreaking space before: ; : ? !
These nonbreaking spaces are present in my file HTML ( ) but disappear in the file epub, and in the files XHTM which are in Content.
For the books, it is a true problem if these nonbreaking spaces miss.
* For the detection of the chapters, it would be necessary that there are 3 levels, and not two (level 1 TOC, level 2 TOC and level 3 TOC), for 1 - parts 2 - chapters 3 - sections
