Sorry this is so basic, but I'm a beginner.

Matt Haughey's blog, [A Whole Lotta Nothing](http://a.wholelottanothing.org/), inserts rosettes under each post title as part of his post template. 

* How can I use Firebug to find where in his CSS these rosettes come from? I've tried inspecting the entry-header element but I'm not seeing anything that that seems tied to the rosettes.
* Am I right in guessing that those rosettes are unicode characters, or is there something else at work?

Thanks!
