java / Servlets / ISO-8859-1而不是UTF-8

Question

I have set character encoding of the response to UTF-8 by

response.setCharacterEncoding("UTF-8");

Despite that, on the client-side, several characters are broken. I had a look at the response's header in the browser tool, and i found out that the encoding was set to ISO-8859-1 .

How can i solve this issue? What is the underlying problem?

Answer 1

I have found the problem:

response.setCharacterEncoding("UTF-8"); must be declared before response.getWriter();
