I did try it dear Kovid (and thanks for your answer).
Here is the debug.log:

And my recipe:
https://gist.github.com/816113
The encoding is set to utf-8 (checked it via: set encoding? in Vim).
Command line:
Code:
ebook-convert es.recipe es.pdf \
--smarten-punctuation \
-vv \
--debug-pipeline debugdir \
--pretty-print \
--test
But the results are still not what expected (in title):
