In Jira workflow, I have added two states: 修改中, 待测试验证. Then in my jenkins job,  I set up the changelog matcher. After I updated the Jira issue workflow status, I have seen the Webhook message in Jenkins, but the job didn't be triggered.

In Webhook message, I find the "fromString" is "\u6dc7\ue1bd\u657c\u6d93\ufffd", the “toString“ is "\u5bf0\u546e\u7974\u7487\u66e2\u7359\u7487\ufffd", but I couldn't convert the unicode of these strings to corrected states(Simplified Chinese).
