I have some problem with displaying the registered trade mark in xml. I wrote a java class to get a xml file from another site, all I did just get that xml and print it out on the browser. First I got an error on the browser, "An invalid character was found in text content.", then I found that the xml file I got didn't specify the charactor set, I added <?xml version="1.0" encoding="ISO-8859-1"?> at the very begining, now the xml can be displayed on the browser, but the register trade mark displayed as +é-« , what should I do?
