Re: Error caused by document length

You could try running epubcheck on the epub produced by pandoc, to see if it points to anything.

So I was wrong about the length: It must be some character or symbol producing the error (only with pandoc, not other EPUB converters). Any idea how to further isolate it, or how to circumvent with a pandoc command or template?

I'll elaborate in case this is what you mean: In the interest of removing variables that might interfere with troubleshooting, I have copied the text from research papers (not just one, but a few), pasted it in notepad, copied and pasted it back into a new word-file (this is more thorough than "clear formatting"), ran this "pure" file through pandoc and I get the error. If I then randomly shorten the file, the error disappears. This is not the case for my "test" file, but only for research papers, which is baffling. I can only assume that pandoc responds to something like a character or in-text references in particular contexts, or as was my original hypothesis, the number of lines or columns in the EPUB.

This is a completely wild guess, but maybe the text in the file is getting normalized upon editing them, whereas the original research paper still contains the unedited, unnormalized text.

I have made a testfile with just the word "test" pasted over and over again, with and without various formatting and with the same length or longer as the proper papers. This file consistently works. But when I attempt to do it with a regular research paper, it only works if I shorten it. Curiously, I can remove either half of the main text, or indeed sections here and there, randomly, and it works, but not with all of them present. I have combed it for special characters or tags, but cannot find any.

It suddenly works when I reduce the length by removing pure paragraph text, even though all the formatted elements (abstract, references, etc) are the same.
