emoji is not saving in utf8mb4_myanmar_ci

I am using utf8mb4_myanmar_ci in table. It's working fine for Myanmar Unicode and can sort the correct order. However, it can store emoji text.

mysql query is like

INSERT INTO `myanmar`.`sort` (`id`, `my`) VALUES (NULL, 'ပြုံးမောင်မောင် ��');

But it only store ပြုံးမောင်မောင် and not include emoji icon.

SHOW TABLE STATUS is showing like that
