We are using v1.6 on a site that pulls in the posts from face book. We did a post on FB and it goes to our twitter account just fine. However the display of the tweet on our website is not correct.
The post originally included a exclamation point after a url link and the FB and Twitter feeds are fine. The Website is including the exclamation point in the a href tag and doesn't link correctly.

PS seems to be working on other punctuation as well. There is another instance of a comma after a link and it's included as well.
