Displaying a checkmark in a report?

Have a report with a table. One of the columns is boolean. I want to show a check mark if it the value is 1 and nothing if it is zero. How can I accomplish this?

Right now part of our datasource query is manually selecting a checkmark character instead of a 1, but this does not come through on the PDF Viewer when viewing a saved PDF from the db.

There is a topic that talks about doing something similar, should get you started.
