How can I make my phone stop displaying emoji?

At some point in the recent past, my phone (a Samsung Galaxy S4) started to display several large swaths of Unicode codepoints as emoji characters--including several that are used for other things, like U+2609, the astronomical symbol for the sun, which is now displayed as a little image of a sun. How can I get rid of these? Everything I find on google is either about how to disable the emoji *keyboard*, or about how to *enable* emoji; what I want is a simple, device-wide system to get rid of emoji altogether and replace them with the symbols that the codepoints are meant to represent. If there isn't any way to do this device-wide, is there at least a way to do it for the Dolphin browser?
