On Linux I also got the right answer. but I am using Windows and visual studio.
On windows I got the wrong answer.

Can you show the output of data.dump(-1, ' ', true)? This should show \u7ec4, but I want to be sure.

@pigLoveRabbit520 Confirmed its an issue of your Console codepage. You are using cp936(Simplified Chinese). It prints 组 as 缁. chcp 65001(UTF8) should print 组 as 组. So its not the issue of nlomann json.

@syoyo I have changed the codepage to 65001, however, I got the wrong result

Please check my previous comment and post the output of dump

(And since I'm neither familiar with Chinese nor Windows - could there be an issue with the font?)
