Convert HTML to PDF by iText & XMLWorker with Polish Letters
I've got a string with an example in it - it works really great, but when I'm adding polish letters, they're gone. I tried something like this:
byte[] byteArray = str.getBytes(Charset.forName("UTF-8"));
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(byteArray);
worker.parseXHtml(pdfWriter, document, byteArrayInputStream, Charset.forName("UTF-8"));
but it doesn't change anything. How to add polish letters?
EDIT: It still doesn't work.
Code:
document.open();
XMLWorkerHelper worker = XMLWorkerHelper.getInstance();
String str = "<html><head></head><body style=\"font-size:12.0pt; font-family:Times New Roman\">"+
"<a href='http://www.rgagnon.com/howto.html'><b>Real's HowTo</b></a>" +
"<h1>Show your support</h1>" +
"<p>It DOES cost a lot to produce this site - in ISP storage and transfer fees</p>" +
"<p>TEST POLSKICH ZNAKÓW: ĄąćCÓ󣳯żŹźĘę</p>" +
"<hr/>" +
"<p>the huge amounts of time it takes for one person to design and write the actual content.</p>" +
"<p>If you feel that effort has been useful to you, perhaps you will consider giving something back?</p>" +
"<p>Donate using PayPalŽ</p>" +
"<p>Contributions via PayPal are accepted in any amount</p>" +
"<p><br/><table border='1'><tr><td>Java HowTo</td></tr><tr>" +
"<td style='background-color:red;'>Javascript HowTo</td></tr>" +
"<tr><td>Powerbuilder HowTo</td></tr></table></p>" +
"</body></html>";
byte[] byteArray = str.getBytes(Charset.forName("UTF-8"));
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(byteArray);
worker.parseXHtml(pdfWriter, document, byteArrayInputStream, Charset.forName("UTF-8"));
document.close();
Maybe someone will find a bug.

I have taken your sample HTML and I have used it to create the ParseHtml2 example. The resulting PDF, html_2.pdf, looks like this:
At first sight, I don't see any issues with the Polish characters.
The code I used looks like this:
public void createPdf(String file) throws IOException, DocumentException {
// step 1
Document document = new Document();
// step 2
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
// step 3
document.open();
// step 4
String str = "<html><head></head><body style=\"font-size:12.0pt; font-family:Times New Roman\">"+
"<a href='http://www.rgagnon.com/howto.html'><b>Real's HowTo</b></a>" +
"<h1>Show your support</h1>" +
"<p>It DOES cost a lot to produce this site - in ISP storage and transfer fees</p>" +

XMLWorkerHelper worker = XMLWorkerHelper.getInstance();
InputStream is = new ByteArrayInputStream(str.getBytes(StandardCharsets.UTF_8));
worker.parseXHtml(writer, document, is, Charset.forName("UTF-8"));
// step 5
document.close();
}
Note that you have defined Times New Roman as the font. It is essential that your OS has access to a font with that name, otherwise you'll still end up with Helvetica.
Also be aware that using non-ASCII characters in source code is considered a crime against good taste. Source code is stored as a text file, but using which encoding? There is no guarantee that your file will be stored as UTF-8, there is no guarantee that a compiler will read it as UTF-8, there is no guarantee that a versioning system will accept UTF-8,... Hence I replaced all UTF-8 characters by their unicode value which allows me to keep the source file in ASCII.
