line breaks in pdf TOC

rjwse@aol.com · 01-28-2021, 04:11 PM

I have converted an epub file to pdf with calibre's converter. The TOC on the end has some lengthy <h1> entries which are so long that they must wrap lines. The page number shows correctly on the second line. The line sometimes breaks at awkward places, even sometimes creates hyphens. I am searching for a method to break the line where I want it to break. I tried several things, but nothing seems to work, including editing of the nav.xhtml and toc.ncx and tweaking the 'edit the toc' feature. Of course, it is possible to truncate the <h1> but sometimes the great length makes good sense. For example: "This is the main Chapter Heading (it is about the following things)" Best regards, Pop

toc titles are plain text so you cannot control line breaking. The ebst you can do is try to substitute nonbreak spaces for spaces everywhere except where you want to allow breaks, but this may not work.

Thanks for your reply. I did try substituting nonbreaking spaces for regular spaces, but the method does not work. Nonbreaking spaces are ignored as such and are treated as regular breaking spaces. To be sure, this is not in any way at all an important problem. I enjoy learning the ins-and-outs of things by tweaking them. Usually, I end up winning "2nd Runner Up" prize at the Tweak-a-thon. But it's a great way to learn. Best regards, Pop
