c# - iTextSharp 5 polish character

Question

I have problem with polish character using itextSharp. I want to create pdf from html. Everything works fine but polish character are missing. I use function lower:

    private void createPDF(string html)
    {
        //MemoryStream msOutput = new MemoryStream();
        TextReader reader = new StringReader(html);// step 1: creation of a document-object
        Document document = new Document(PageSize.A4, 30, 30, 30, 30);

        // step 2:
        // we create a writer that listens to the document
        // and directs a XML-stream to a file
        PdfWriter writer = PdfWriter.GetInstance(document, new FileStream("Test.pdf", FileMode.Create));

        // step 3: we create a worker parse the document
        HTMLWorker worker = new HTMLWorker(document);

        // step 4: we open document and start the worker on the document
        document.Open();
        worker.StartDocument();

        // step 5: parse the html into the document
        worker.Parse(reader);

        // step 6: close the document and the worker
        worker.EndDocument();
        worker.Close();
        document.Close();
    }

And Try use it:

createPDF("????????ńóó??????");

I try set:

BaseFont bf = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, Encoding.UTF8.HeaderName, BaseFont.EMBEDDED);

        writer.DirectContent.SetFontAndSize(bf, 16);

But it dosen't work

Do you have any idea??

Just to roll together what @Mark Storer said:

private void createPDF(string html)
{
    //MemoryStream msOutput = new MemoryStream();
    TextReader reader = new StringReader(html);// step 1: creation of a document-object
    Document document = new Document(PageSize.A4, 30, 30, 30, 30);

    // step 2:
    // we create a writer that listens to the document
    // and directs a XML-stream to a file
    PdfWriter writer = PdfWriter.GetInstance(document, new FileStream("Test.pdf", FileMode.Create));

    // step 3: we create a worker parse the document
    HTMLWorker worker = new HTMLWorker(document);

    // step 4: we open document and start the worker on the document
    document.Open();

    // step 4.1: register a unicode font and assign it an allias
    FontFactory.Register("C:\Windows\Fonts\ARIALUNI.TTF", "arial unicode ms");

    // step 4.2: create a style sheet and set the encoding to Identity-H
    iTextSharp.text.html.simpleparser.StyleSheet ST = New iTextSharp.text.html.simpleparser.StyleSheet();
    ST.LoadTagStyle("body", "encoding", "Identity-H");

    // step 4.3: assign the style sheet to the html parser
    worker.Style = ST;

    worker.StartDocument();

    // step 5: parse the html into the document
    worker.Parse(reader);

    // step 6: close the document and the worker
    worker.EndDocument();
    worker.Close();
    document.Close();
}

And when you call it wrap your text in a font using the name you registered above:

createPDF("<font face=""arial unicode ms"">????????ńóó??????</font>");
