OK, I'll take a stab at answering this now I've had a tinker. It looks like Josefin Sans does not have a glyph for ellipsis (…), so Chrome is swapping out that line. There are other people experiencing this with other Google fonts:
- https://code.google.com/p/googlefontdirectory/issues/detail?id=204
- http://wordpress.org/support/topic/a-problem-with-ellipsis-the-google-font-story
The lack of ellipsis can be tested here
Either swap the ellipsis for three periods and risk the wrath of typophiles, or change the font I'm afraid.
