sgcWebBrokerBridge_IndyHTTP2 with extended characters

Hi Sergio, I developed a REST server in http2, based on your example Demos\40.DataSnap\Server_Indy_HTTP2\sgcWebBrokerBridge_IndyHTTP2.dproj, but despite having tried various charset and contenttype settings, I cannot correctly display the extended characters.
Then try also by modifying the files serverfunctioninvoker.html and reversestring.html by inserting extended characters in the text.
I would like to understand if I am doing something wrong or if it is a library problem.

P.S. The extended characters passed through the "ServerFunctionInvokerHTMLTag" function are correctly displayed, as you can see from the attached files.

thanks
