Ok, I fould de clue: the problem is Jetty, using Tomcat everything works fine.
I can search diacritics (I found Jetty required an extra UTF8 encoding on query values in the url) AND no more problems in responses with field containing XML with diacritics and Euro sign (and everything else I suppose). It's a Pity because Jetty is much more slimmer to deploy and install and perhaps faster, but anyway I think these problems should be documented in some manner.
