Alternate checkboxes

[jcesguerram]

Hi! I would like to change some of the icons of the alternate checkboxes. i use another thene but i have the css snippet.
in the snippet i'm guessing the "\ec10" part is ehat determines the icon, but i don't know what those codes correspond to. does anyone know where they come from?
