displaying arrows on IE, Ios, Android...

[tchobello]

Hello

I have some issues displaying arrows in all four directions in JS.

Code: Select all

this.addActionButton( 'breakwall_'+action.character_id+'_'+action.dir, _("Break the wall")+' 🠈', 'onBreakWall' );

&#129032 to &#129035 aren't displayed correctly in all platforms.
I've replaced them with &#x21C7 to &#x21CA, working everywhere with ugly double arrows.

Does anyone know how to display something nicer, resembling the right allowing you to switch to another table ?
Thanks a lot.
