Override validChar method, try

TextField textField = new TextField(){
        public boolean validChar(String c) {
            if (((c.charAt(0) > 'a') && (c.charAt(0) < 'z')) || ((c.charAt(0) > 'A') && (c.charAt(0) < 'Z'))) {
                return true;
            }
            return false;
        }
    };

You must do it by hand. Get the first char and check it against all other until you find a different char. Or You can create a regexp out of the first char and match your value against it.

edit : The question has completely changed. This answer was meant for another question. So is the next answer.
