Various problems in Servlet garbled

Servlet Chinese garbled characters
Insert the following word into Servlet doPost and the jsp that calls Servlet.
[Html]
Request. setCharacterEncoding ("UTF-8 ");
Response. setCharacterEncoding ("UTF-8 ");

[Html]
<% Request. setCharacterEncoding ("UTF-8"); %>
<% Response. setCharacterEncoding ("UTF-8"); %>
Keep the code on both sides consistent.

Enter a space in the Servlet
It is the same as a space in HTML code. The width of the four "& nbsp" characters is the same as that of a Chinese character.
