// Description : This is a PHP5 class for generating PDF files
// on-the-fly without requiring external
// extensions.
//
// IMPORTANT:
// This class was originally derived in 2002 from the Public
// Domain FPDF class by Olivier Plathey (http://www.fpdf.org).
//
// Main features:
// - supports all ISO page formats;
// - supports UTF-8 Unicode and Right-To-Left languages;
// - supports document encryption;
// - includes methods to publish some xhtml code;
// - includes graphic and transformation methods;
// - includes bookmarks;
// - includes Javascript and forms support;
// - includes a method to print various barcode formats using an improved version of "Generic Barcode Render Class" by Karim Mribti (http://www.mribti.com/barcode/) (require GD library: http://www.boutell.com/gd/)
// - supports TrueTypeUnicode, TrueType, Type1 and encoding;
// - supports custom page formats, margins and units of measure;
// - includes methods for page header and footer management;
// - supports automatic page break;
// - supports automatic page numbering;
// - supports automatic line break and text justification;
// - supports JPEG, PNG anf GIF images;
// - supports colors;
// - supports links;
// - support page compression (require zlib extension: http://www.gzip.org/zlib/);
// - the source code is full documented in PhpDocumentor Style (http://www.phpdoc.org).

* Note: for the standard fonts, the font metric files must be accessible.

* //Arial bold 14
* $pdf->SetFont('Arial','B',14);
* //Removes bold
* $pdf->SetFont('');
* //Times bold, italic and underlined 14

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

*
* Encoding of a single character from an ISO 10646 character value to

*
* 1) If U < 0x10000, encode U as a 16-bit unsigned integer and

*
* 2) Let U' = U - 0x10000. Because U is less than or equal to 0x10FFFF,
* U' must be less than or equal to 0xFFFFF. That is, U' can be
* represented in 20 bits.
*
* 3) Initialize two 16-bit unsigned integers, W1 and W2, to 0xD800 and
* 0xDC00, respectively. These integers each have 10 bits free to
* encode the character value, for a total of 20 bits.
*
* 4) Assign the 10 high-order bits of the 20-bit U' to the 10 low-order
* bits of W1 and the 10 low-order bits of U' to the 10 low-order
* bits of W2. Terminate.
