在IE8中使用“另存为” execCommand将XML文件保存为ANSI格式，而不是UCS2-Little Endian

Question

I am currently trying to save an XML data using "SaveAs" execCommand from Javascript in Internet Explorer 8 only.I am using document.write(xml) to write the xml content after i open a window.The document object in IE8 uses a saveAs Exec Command to allow the user to save the xml file in the local folder.The XML file is generated but it doesnt set the encoding to my preferred type for a different interface where i need to send this XML which is ANSI/UTF-8 encoding.I can only save the XML in UCS2 little Endian encoding format.Below is the code i am using.

 var location = "D:\\export_to_MCT"+dateTime+".xml";

    var xml = tmpSelectedConfigurationXML.transformNode(xslDoc);// XML Is generated here
   alert(xml);
     **var testlink = window.open  ("about:blank","_blank","toolbar=no,status=no,menubar=no,scrollbars=no,resizable=no,left=10000, top=10000, width=10, height=10, visible=none");
     testlink.document.write(xml); //fileData has contents for the file
testlink.document.close();
testlink.document.execCommand('SaveAs', false, location);**
testlink.close();

My purpose is to save the xml in ANSI/UTF-8 encoding without BOM format.I cant use Scripting.FileSystemObject method of ActiveX object.Please suggest

Strip out unsupported characters from XML

Since not all UTF-8 characters are accepted in an XML document, you'll need to strip any such characters out from any XML that you generate. After reading the xml file replace '/[^\\x{0009}\\x{000a}\\x{000d}\\x{0020}-\\x{D7FF}\\x{E000}-\\x{FFFD}]+/u' with ''

or try with testlink.document.charset="UTF-8";
