Yes, thanks for pointing out. There is a parameter --latex that should
be set to --latex=xelatex, shame on me. Now I'm trying to cope with it,
seems really good. Even though I have the feeling native solution seemed
a little faster (might be due to huge amount of such calls and many perl
processes spawning... but that's just price for that comfort)
