APOSTROPHE - PROBLEMS ON TWITTER

BUG! Since a week ago Twitter is changing the messages! It occurs when I enter on Twitter Search. Everytime a person write the apostrophe, appears "&APOS" followed by an S or T, or other sign. It must be corrected by Twitter! I never used this expression before and it appeared on a tweet I wrote. And I see it on people I'm following much more than 100 times! Oct19, 2009
