Why is there a question mark when a mobile phone sends a text message to someone?

If you send an email with traditional Chinese characters or enter a large paragraph of text. And the information appears: it cannot be displayed or completely displayed, garbled, and some characters in the information content are displayed as spaces or directly omitted or similar. Then you don't have to worry. Because it's not your fault,

It's the other person's cell phone. He uses either apples or domestic ones.

There are some differences between Apple and Nokia. However, my address book is garbled only when I change my mobile phone (Nokia and Apple are used interchangeably) without changing my card. I just heard it, so I also mentioned it.

However, the domestic computer can not only display a little too long information normally, but also can not identify and analyze traditional Chinese. You can see how obvious the gap is by logging in to qq with domestic and brand-name machines respectively. All the time. You can't read the words he can't type. It's either a bunch of spaces or a mess,

If it is not the above reasons, it is your information setting problem.
