Answer 1

I think this because of some characters is encoded as 2 to 4 bytes.

Anyway this snippet can do the trick

TextField(
     onTap: (){
          if(controller.selection == TextSelection.fromPosition(TextPosition(offset: controller.text.length -1))){
             setState(() {
                 controller.selection = TextSelection.fromPosition(TextPosition(offset: controller.text.length));
             });
           }
     },
     controller: controller,
     ...
);
