Is it possible to make Windows git bash support chinese

I am trying to use curl (v8.6.0) to send the HTTP request to sever side under Windows git bash terminal. The server side is a Java spring boot application. When the curl JSON content contains Chinese words, the server side shows this error:

The jackson was the default JSON parser for spring boot application, and this server side works fine with a Google Chrome xhr request, but failed with the curl request from Windows git terminal. Am I missing something? It looks like this git bash has some encoding issue in Windows. What should I to to make the windows git bash support Chinese words? This is the curl info:
