	/**
	 * PROBLEM WITH THE WRONG ENCODING SET TO THE XML STRING REPRESENTATION OF THE CHART TEMPLATE INSIDE THE xmlObject INPUT PARAMETER. FOR THIS
	 * APPLICATION, IT IS ALWAYS SET TO UTF-8, EVEN IF WE APPLY THE XML TEMPLATE WITH SOME DIFFERENT ENCODING (e.g. ISO-8859-1).
	 * 
	 * This line (encoding of the format) is commented due to the problem stated in the KNOWAGE-775 JIRA issue (title
	 * "COCKPIT-Chart: letters with accent are not correctly decoded").
	 * 
	 * It is found that the XML template of a chart has the UTF-8 encoding set in its header, no matter what is the encoding set on saving of the chart
	 * document (or uploading of the template with some different encoding, e.g. ISO-8859-1). It is not clear why this happens.
	 * 
	 * THE WORKAROUND: the encoding setting of the format will be skipped in order to avoid misbehavior and wrong encoding of the XML string representation
	 * (inside the xmlObject input parameter). This way we are keeping all the details provided in the template, such as specific Italian letters (such as
	 * à, è, ò etc.). Otherwise, this line would encode that XML string with the default encoding type (XML_HEADER_DEFAULT_ENCODING), that is ISO-8859-1. If
	 * we let this happen, we would lose mentioned specific letters and we will start getting weird ones on the chart (such as è).
