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,
...
);
