Check Text ( C-17804r1_chk )

Ask the application representative to review web pages, and determine if the application sets the character set. Perl After the last header look for print "Content-Type: text/html; charset=utf-8\n\n"; PHP. Look for the header() function before any content is generated header('Content-type: text/html; charset=utf-8'); Java Servlets. Look for the setContentType method on the ServletResponse object Objectname.setContentType ("text/html;charset=utf-8"); JSP. Look for a page directives <%@ page contentType="text/html; charset=UTF-8" %> ASP Look for Response.charset <%Response.charset="utf-8"%> ASP.Net Look for Response.ContentEncoding Response.ContentEncoding = Encoding.UTF8; 1) If the application representative cannot demonstrate the above, it is a finding.
