Restrict special characters from iOS / Android roku remote app for DynamicCustomKeyboard

I would like to restrict users from being able to type any special characters (i.e. $%^&) in my DynamicCustomKeyboard from the iOS / Android roku remote keyboard. My DynamicCustomKeyboard only allows for alphanumeric values, but when used on the roku mobile app keyboard, users can type any character possible. How can I allow only alphanumeric values?
