Prevent Microsoft Word automatically applying Apple Color Emoji font substitutions

I'm on macOS Ventura 13.6.7 using Microsoft Word 16.87. When I try to paste in a unicode character like ☑ ("Ballot Box with Check"), Word automatically chooses "Apple Color Emoji" as the font (making it look like this: ), and I'm not able to change it. I think it doesn't look professional, and I would like to disable it completely, if possible, or at least change the font back for individual instances. How can I do that?
