Is it possible to use a random Unicode character as a bullet for a list?

I want to add custom bullet style to my document. For example, I would like to make it empty squares. There is such unicode character - empty square. So it would be convinient for me just to select a unicode character as a bullet for a list, so I don’t have to draw it as a custom graphics (and deal with graphics at all). Is it possible? If not, it is probably worth to implement, because it is simple and convinient.

I think editing the list or creating a new one.
