How to support Chinese characters in new WebSocketClient()

[9992800]

when I add parameters at the end of url as follow:

wss:https://xxx.com/online_test?system=-1&80010086=-1&80010087=-1&userName=我是.

WebSocketClient() translate the Chinese words to ??:3

I try to change the headers , but failed.
Map<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");

Still wrong :

write(293): {GET /online_test?system=-1&80010086=-1&80010087=-1&self=3&userName=??:3&token=a45dac5adfa4w HTTP/1.1

Hello @9992800,

you have to html encode all the chinese characters to valid html.
