The display of control characters appear in the Author column on the forums.

This is visible when comparing the existing jboss.org and POCv2 forums. for the Transactions User forum. On the current forum the Author column displays the username. Whereas the POCv2 Author column displays the first and last names of the user.

Can either strip the control characters before rendering content or clean up the original data.

Note, the control characters are visible when looking at the user details (first and last name) on the current Community system. So this is not a new issue, rather it is made visible on POCv2 having changed the source field value for the Author column.
