keyboard symbols

[Albert Cahalan]

I notice that some keyboards lack the multiplication
and division symbols. Providing them for all kids
would be good, even if they need to move elsewhere.

Other useful things found in Unicode:

bullet
star
heart
smiley
skull-and-crossbones
musical flat
musical natural
musical sharp
copyright symbol
registered trademark symbol

check mark
dagger

center dot (math)
set union symbol
set intersection symbol
plus or minus symbol
power of -1

spade
clubs
diamond
