I have an epub (G. H. Hardy's "A Mathematician's Apology") that contains cube root symbols (Unicode char 0x221B), and regardless of what font I choose for text display on the reader, this symbol just displays as a square hollow box. If I view the same epub on the PC using either Sigil or the Calibre ebook viewer, the symbols show correctly. I also have the Charis SIL Modified and Charis SIL compact fonts that I downloaded from here installed on the Aura HD, and they also just show the symbol as a hollow square, though the same font on the PC shows the cube root symbol correctly.

The Aurd HD is running firmware 3.1.1.
