Driver configuration seems to be ok. Ensure that you get correct UTF-8
strings from the web container. Note, new String(italian.getBytes())
in your configuration will replace all accented chars with '?', so if
such code is somewhere in the application, it will corrupt characters.
You can modify default encoding for the VM by specifying
-Dfile.encoding=XXXX (UTF-8/Cp125X/ISO8859-X).

If you are 100% sure that you give correct unicode string to JayBird
and lc_ctype is UNICODE_FSS, but it still corrupts unicode characters
that are not in default encoding, I would be very grateful for a test
case.
