Unicode char comparison puzzle

[Eric Rechlin]

The font used by the Prime is called Prime Sans, and it's a modified version of Google's free Droid Sans font. The ttf file is in the Fonts folder of the HP Prime Virtual Calculator installation, so you can look at that with your favorite font analysis tool to see what characters it supports. A tool I use shows 51280 different characters, but it doesn't seem to have any of the emoji characters.
