I’m trying to make an Instant Messaging program in Unity, using Scandinavian Runes instead of letters. I
want to use the Mobile Keyboard that Unity already has so I don’t have to make my own. But I’m trying
to figure out if I can change the font for the letters on the keyboard. I’ve checked all over the documentation
and it says nothing on being able to do that. But I thought I’d ask here to make sure. If this can’t work I guess I’ll just have to try and make my own keyboard UI.
Any answers will be greatly appreciated. 
As far as I know, Unity doesn’t include a mobile keyboard of any sort. When you’re running a mobile Unity app and tap inside a text input field, the application just tells your OS to bring up your virtual keyboard. So the only way I could picture using the built-in keyboard and having it work the way you want is if the user already has a Scandinavian Rune keyboard installed (is there even one?) and it’s set as their default keyboard.
Pretty sure you’d have to incorporate your own custom on-screen keyboard instead.
Alright. At least I have more of an idea of what to do now. Thanks for the Info.
