matching mega menu arrows

I have theme menus that I have to apply custom CSS to match the style of my max mega menus. I am struggling with the arrows for the drop down indicators. In max mega menu, I have selected: Up, Down, Left, Right “Alt2″s. I need to know the equivalent code to add to the menu content.
So far I have come up with /2304 for the down arrow, but it doesnt quite match up.
.header-nav li.account-dropdown:after { content: ‘2304’;}

Can you please give me the corresponding numeric (decimal) or css (hex) values for these 4 arrows?
