mtext bullet showing up as "S"

Hi-

I'm posting this in both regular AutoCAD and C3D since it's seems like a regular AutoCAD problem, but we use C3D.  Since we switched to 2014, when we try to do bullets in mtext in any textstyle, the bullets are the letter "S".  Does anyone know what would have caused this and/or how I can fix it?

Thanks so much for your help!
