Needing help getting certain unicode characters to work in Unity

I have some unicode characters that I'd like to use in my code/project, but when I try to use them, they just turn up blank in the game. For a while, I never could even get these characters into my code, but since I switched over to Visual Studio Code, I can now at least copy/paste these characters from Word into it.

Here is a little background that may shed some light on my issues. These characters are within a certain font (I have this font already in my project and attached to the appropriate text object). If, for example, I want to use these characters in Word, I have to switch to this font, then go into the special characters section and select them manually. There is a way to do this easier via a special keyboard program, but I don't use it.

The unicode characters range from 104B0 - 104FB.

Any ideas on what I should do?
