Converting pandoc generated HTML to ePUB with Calibre

Hi,

I recently formatted a (very long) book with pandoc. I find pandoc nice and really convenient for generating HTML. Then I convert the HTML into ePUB using calibre. Pandoc itself can generate ePUB, but the process is very automatic, and not many things can be customized. For instance, TOC levels cannot be customized (only chapters appear in TOC). That's the reason I use calibre to convert from HTML to ePUB: using the command line I can nicely control a lot of stuff about the generated ePUB (cover, TOC, etc...).

The problem is that the book I'm converting is in Spanish, and some of the chapter's titles contains accents (á é í ó ú). For every section element (h1, h2, etc...) pandoc generates and id you can use to refer to that element in the text. For example, if a chapter is entitled "Introducción", pandoc generates this into the HTML.

Code:
<h1 id="introducción">Introducción</h1>
Calibre crashes if some hX header contains non-ascii characters.

Here's calibre's output.

Code:

  File "xpath.pxi", line 214, in lxml.etree._XPathEvaluatorBase._raise_parse_error (src/lxml/lxml.etree.c:112698)

Is this a normal calibre behaviour or it's a pandoc's bug?

Thanks in advance for your help.

The problem is the non ascii characters in the id attribute. That is illegal in XHTML, as far as I recall.
