Some funny symbols showing up in Digg Counter

I encountered one problem with the Digg Counter, When I was just logged into my Digg account, while viewing my friends articles - I found an issue with the Digg Counter, it is showing up some funny symbols like in the screen shot below (the one which I have pointed with blue arrow).



I would like to inform the DIGG Team to check with this once, as I am worried does this may effect the application in running the things properly. I am very much fan of DIGG for the work they do by introducing some good applications which full fills the Users aspects, so once again I would like to request the team to look into this.....
