Unification spaces of titles

In HTML it's not problem (browser ignores spaces), but this problem is reflected e.g. in PDF output. Titles is not generated equally and e.g. in table of content are not aligned.

I'm not seeing any of the strange spacing behavior you're reporting. What version of pandoc did you use, how did you install it, and what is the exact command you are using to convert? You might also try reproducing on http://johnmacfarlane.net/pandoc/try

$ cabal install pandoc

I can't reproduce what you're seeing. See Try pandoc. Everything looks fine.

What exact pandoc command are you using to convert your input? For diagnostics, can you try it with pandoc -t native and post the result?

[romanmatyus]

Strange behavior. Now, when I create new file with markup text from first comment, I get correct output.

But, when I use different input, I get again bad output.

input test.md:

# Návod na prevod detailného návrhu do PDF

## Inštalácia prostredia

## Prevod do PDF

$ ~/.cabal/bin/pandoc test.md -o test.html

output:

<h1 id="návod-na-prevod-detailného-návrhu-do-pdf">Návod na prevod detailného návrhu do PDF</h1>

See Try Pandoc - fails!

I really not find terms with that entry fails. I do not see a relation.

Note the \160 (a nonbreaking space) at the beginning of the string inside the headers.

The most likely reason this would be there is if your input contains a nonbreaking space between the ## and the first letter. Just use a regular space there and you should be fine.

[romanmatyus]

Yes, thanks. I understand.

But by my it's bug. Minimal it's not expected behavior.

I vote for crop input about nonprinting characters. Bad idea? Current stats can cause WTF effect (like me).

[jgm]

No, I don't regard it as a bug. Nonbreaking spaces are never ignored in pandoc, and that's a feature -- for those rare cases where you really want a space.

I do not think totally ignore. My idea is only on start and end titles. In this case is not reason for their existence.

[jgm]

In my view it is best to be consistent in treatment of nonbreaking spaces, and not second guess what users might want to do.
