Solve the Problem of garbled characters when the jsp: include file is referenced, jspinclude

Before explaining the problem, let's take a look at the garbled page in the iframe on the left side of the picture below;

This is the garbled code that makes me Tangle for a while:

This error occurs when the <jsp: include> label is referenced on this garbled page;

It is said that when jsp include dynamic files (jsp files), code can be added to the header of the included jsp file:

<% @ Page language = "java" contentType = "text/html; charset = UTF-8" pageEncoding = "UTF-8" %>
