This rule is defined by the following XPath expression:
//Content[ not(Element[@Name="meta"][ Attribute[@Name="content"]/AttributeValue[contains(string:lower-case(@Image),"charset=utf-8")] ]) and not(JspDirective[@Name='page']/JspDirectiveAttribute[@Name='contentType'][contains(string:lower-case(@Value),"charset=utf-8")]) ]
Example:
Most browsers should be able to interpret the following headers: <%@ page contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %> <meta http-equiv="Content-Type"� content="text/html; charset=UTF-8" />
