File encoding
You can specify and invoke the character encoding in XML files, XHTML and HTML files, and JSP files in different ways. Because many editors expect to find encoding in source files, specify the encoding in each one of your source files.
For JSP files, you might use the pageEncoding attribute, the contentType
attribute, or both attributes in the page directive, as shown in the
following example:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
For XML files, you might use the encoding pseudo-attribute in the xml declaration at the start of a document or the text declaration
at the start of an entity, as in the following example:
<?xml version="1.0" encoding="iso-8859-1" ?>
For XHTML and HTML files, you might use the <meta> tag inside the <head> tags, as shown in the
following example:
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
