Thx Kovid,
Works better (the CSS for the custom styles are OK with .docx), but there is 1 drawback with this hint:
- The conversion from ODT to DOCX by soffice is not handling correctly dialog style (one more unbreakable space in front of the § and only for roman.dialogue).
But I will try to go along your line, and correct the conversion once in the EPUB format. And if I have enough heart and time, I might have a look at the source, but don't expect it very soon
