Can apple add Myanmar script

The Burmese alphabet is added however some the Karen alphabet cannot be seen even though they’re both using Myanmar script. The Karen alphabet have tone characters that are not present in the Burmese alphabet therefore when you write in Karen, some keys are not shown but shows a box with question mark inside. Can apple add the Karen script unicode? And also add the Karen language to iPhone languages please. The Karen language is spoken with 7 to 10 millions people around the world. Sample of a Karen sentence, ယမ့ၢ်ဝဲပှၤကညီဖိ ယအိၣ်ဖျဲၣ်ထီၣ်လၢကညီကီၢ်. As you can see not all the Karen letters can be seen because apple only recognize the Burmese alphabet and did not include the Karen. Please add the Karen Unicode.
