When loading xml string to scala.xml.Elem, the method throws error saying org.xml.sax.SAXParseException: Content is not allowed in prolog. It looks like BOM (byte order mark) issue because xml to be parsed contains BOM value <U+FEFF> at the head of xml. Generally what is a canonical way to handle this (though I can simply remove it)?
