[boost] An invalid XML character (Unicode: 0x8) problem because of property_tree::xml_parser::write_xml

Hi, I have used the following C++ code to generate the xml boost::property_tree::ptree ptResponse; // Populate the tree from the Microsoft Outlook contactsstd::stringstream buf; const std::string enc("utf-8"); boost::property_tree::xml_writer_settings<char> settings(' ', 0, enc); boost::property_tree::xml_parser::write_xml(buf, ptResponse, settings); This works fine. But in one of the customer's machine, when reading the this(xml content) in a JAVA program. I get the following error An invalid XML character (Unicode: 0x8) was found in the element content of the document. Any help in solving this is appreciated. Regards,Rohan
