		/**
		* Sets the font used to print character strings. It is mandatory to call this method at least once before printing text or the resulting document would not be valid.
		* The font can be either a standard one or a font added via the AddFont() method. Standard fonts use Windows encoding cp1252 (Western Europe).
		* The method can be called before the first page is created and the font is retained from page to page.
		If you just wish to change the current font size, it is simpler to call SetFontSize().
		* Note: for the standard fonts, the font metric files must be accessible. There are three possibilities for this:<ul><li>They are in the current directory (the one where the running script lies)</li><li>They are in one of the directories defined by the include_path parameter</li><li>They are in the directory defined by the FPDF_FONTPATH constant</li></ul><br />
		* Example for the last case (note the trailing slash):<br />
		* <pre>
		* define('FPDF_FONTPATH','/home/www/font/');
		* require('tcpdf.php');
		*
		* //Times regular 12
		* $pdf->SetFont('Times');
		* //Arial bold 14
		* $pdf->SetFont('Arial','B',14);
		* //Removes bold
		* $pdf->SetFont('');
		* //Times bold, italic and underlined 14
		* $pdf->SetFont('Times','BIU');
		* </pre><br />
		* If the file corresponding to the requested font is not found, the error "Could not include font metric file" is generated.
		* @param string $family Family font. It can be either a name defined by AddFont() or one of the standard families (case insensitive):<ul><li>Courier (fixed-width)</li><li>Helvetica or Arial (synonymous; sans serif)</li><li>Times (serif)</li><li>Symbol (symbolic)</li><li>ZapfDingbats (symbolic)</li></ul>It is also possible to pass an empty string. In that case, the current family is retained.
		* @param string $style Font style. Possible values are (case insensitive):<ul><li>empty string: regular</li><li>B: bold</li><li>I: italic</li><li>U: underline</li></ul>or any combination. The default value is regular. Bold and italic styles do not apply to Symbol and ZapfDingbats
