Currently page titles can't contain any
formatting, or many special
symbols. This has been discussed on this list before and the general
consensus seemed to be that allowing the capitalisation of the first
letter to be specified, and allowing italics would be improvements.
However, nothing has yet been implemented AFAIK.
There is an option of alternative titles in MediaWiki, but this option
is disabled on Wikimedia sites (IIANM). But some wikis use
CSS+JavaScript workarounds for that, see e.g.
http://it.wikipedia.org/wiki/Template:Titolo_errato
a similar trick could be used for italics.
