Typing/Virutal keyboard for controller-only games?

Hi Everyone!

My group is working on a game that would ideally be controller only, but we have a character customization screen that asks players to enter a name for their character/save file.

Is there anything built into unity already that brings up a virtual keyboard when asked? Or should I just implement my own virtual keyboard and GUI that I can pop up onto the screen when needed.

How do other people do text input for their controller games? I've taken a look at the store for virtual keyboards, but it seems that they work under the assumption that there is mouse input, which isn't useful for us.

Thanks for your time.
