如何在html中显示某些类型的字符

Have to dispaly this ü in html

I do get the reponse from the server as ü,

But the browser displays it as ü how to prevent this from happening i dont know how many more these kind of special characters are possible

Response Connection:Keep-Alive Content-Type:text/html; charset=utf-8 i guess thiss is done but still get same error

You must set the Content-Type header to use UTF-8 charset as header("Content-Type:text/html;Charset=UTF-8"); and important, the php file must be using too the UTF-8 charset
