Default Emoji's not working

is anyone having issues with the emoji's not showing up? couldnt get them to show up on either 4.3 or 4.4. i can send one and see it but if someone sends me one it doesnt show up. my wife tries with her s4 to send them and its just a blank message. not even a square shows up. i installed the kii keyboard and the plugin for them and still no go.
