You can add non-english characters to your XML using PHP and let FusionCharts show them. For this you woudl need to add the BOM to the file.

If you are using dataURL method use these lines:

header('Content-type: text/xml');
echo pack("CCC",0xef,0xbb,0xbf); //adding BOM characters
echo strXML;

If you are using dataXML method you would need to save the PHP file with UTF-8 encoding with BOM. You can do this using Notepad or Drreamweaver etc.
