title: How to handle the illegal HTML characters in XSL
body: <p>I have an XML file which stores data. I am using an XSL to generate HTML files from that XML file. When I try to do that I get the error <code>Illegal HTML character: decimal 150</code></p>
  
  <p>I am not allowed to change the XML file. I have to map that one and many other illegal characters to a legal character (it can be any) in XSL. So it has to do that mapping in a generic way not only for one type of character.</p>
