L''''amore''' e blah blah l''''informazione'''... L''''amore''' e .... blah '' blah...
Actually, those examples work correctly :-) The three words are in bold, the right apostrophes appear and the last "blah" is italics.
I think bold normally works fine, it's italics that are a problem because "apostrophe-italic" looks just like "bold". "apostrophe-bold" doesn't look like anything else.
