Can't input Chinese characters in PHP CLI?

My system: debian8+php
Under DBEIAN8, use Lxdterminal to enter and display Chinese characters, which can be entered and displayed in bash.

You can also enter and display Chinese characters in the Python shell

You can display Chinese characters in the PHP cli (or PHP shell, or interactive mode), and you cannot enter Chinese characters.
Php-a
Interactive mode Enabled

php > Echo Pack ("H12", "e4b8ade69687");
Chinese
You can display Chinese characters.

Unable to enter Chinese characters.

I click the ENTER key, or choose 1, Chinese characters can not be entered into the inside.

Excuse me, how to solve?
