Special characters replaced with emoji
How do I keep special characters from being automatically replaced with emoji? I am trying to insert special characters into a Powerpoint presentation (16.13.1) using the character viewer, as I have done probably hundreds of times before, but now the characters are being replaced with emoji versions, even if I specifically select a plain font variation. I don't want the emoji version; I need the character to match the colors and styles in the rest of my text.
I tried selecting each of the font variations; each one was automatically replaced with emoji. I also tried placing the desired symbols in a plain text document using Text Edit. They appeared correctly in the Text Edit document, but when I tried to copy from there into Powerpoint, they were replaced by emoji again.
Any guidance would be greatly appreciated!
I am working on a Macbook Pro, running OS X El Capitan, version 10.11.6.
