TextMesh Pro Control-i (^i) adding tab

Having an issue with TextMeshPro InputField using the ASCII Character 9 (Horizontal Tab) when I'm setting up a shortcut for Italics.

I'm building a simple text editor using rich text tags and universal hotkeys. Underline and Bold work just fine as the ASCII control functions are not inputted into the text box.

Control-b (^b) - start of text
Control-u (^u) - negative acknowledgement

Is there a way to turn off Control-i (^i) from being inputted. The other way I was going to do this was to use a mediator that listened to the Input class and changed the text of the box from there.(Not Ideal)

 

Figured it out, ended up using an additional TMP_InputValidator that was toggled when either control button was held. The override class used is as follows:

Code (CSharp):

1. [CreateAssetMenu(fileName = "New ControlValidator", menuName ="TMP_Validators/Control")]
2.     public class TMP_ControlValidator : TMP_InputValidator
3.     {
4.         public override char Validate(ref string text, ref int pos, char ch)
5.         {
6.  
7.             if (char.IsControl(ch))
8.             {
9.                 return '\0';
10.             }
11.  
12.             pos++;
13.             text += ch;
14.             return ch;
15.         }
16.     }
