Why can't some words be displayed when my mobile phone receives someone else's short message, but a box! ! Reward 100 points

Every mobile phone has its own "font", just like ordinary mobile phones can recognize Chinese characters and English, but many mobile phones can't recognize traditional Chinese characters, Japanese, Korean and other characters, so they have boxes, and some symbols can't be recognized, and they also display boxes, hehe, for example).

I hope my answer is helpful to you.
