Define the key "i"

I am using a Turkish keyboard and I want to define the key “İ” (In Turkish keyboard has separate buttons for “i” and “ı”(i without a dot)) however I can only write

 if(Input.GetKeyDown(KeyCode.I))
        Description.text = "Sarı bir ışık hüzmesi arıyorsun.";

but I cannot write

if(Input.GetKeyDown(KeyCode.İ)
        Description.text = "Sarı bir ışık hüzmesi arıyorsun.";

does anyone know how to define uppercase “i”?
Thanks for now.

You could try and define the button inside the input manager

Input.anyKeyDown && Input.inputString.Equals(“i”)

You can use this combination.
