Itextpdf HTML to PDF containing Cyrillic letters

I asked another question about this issue, but I couldn't get it to work. I changed my code so it now looks something like this:

import java.io.FileOutputStream;
import java.io.StringReader;

import com.itextpdf.text.Document;
import com.itextpdf.text.PageSize;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.tool.xml.XMLWorkerHelper;
public class HTM {

    public static void main(String ... args ) {
        try {
            Document document = new Document(PageSize.LETTER);
            PdfWriter pdfWriter = PdfWriter.getInstance
                           (document, new FileOutputStream("C:\\testpdf.pdf"));
            document.open();

            XMLWorkerHelper worker = XMLWorkerHelper.getInstance();

            String htmlString = "<html><head>"
                    + "<meta http-equiv=\"content-type\" content=\"application/xhtml+xml; charset=UTF-8\" />"
                    + "</head><body>"
                    + "<h1>Zdravo ј!</h1>"
                    + "</body></html>";


            worker.parseXHtml(pdfWriter, document, new StringReader(htmlString));
            document.close();
            System.out.println("Done.");
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }
}

My problem is that cyrillic characters are not displayed in the pdf. I know how to make a simple pdf with different encodings and fonts, but I want to convert an html file or string (in my case it is an html string) to pdf. Thanks in advance.

I tried a lot of things, but every time I was missing something. Thanks to @BrunoLowagie and @SubOptimal. Here's my code that I am running for custom fonts. It also contains plain html as a string, but the comments show (how this is done) how this can be done with the actual html and css files.

public class HtmlToPdf {
    public static final String DEST = "/home/christian/Desktop/testDoc.pdf";

    public void createPdf(String file) throws IOException, DocumentException {
        // step 1
        Document document = new Document();

        // step 2
        PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
        writer.setInitialLeading(12.5f);

        // step 3
        document.open();

        // step 4

        // CSS
        CSSResolver cssResolver = new StyleAttrCSSResolver();
        // CssFile cssFile = XMLWorkerHelper.getCSS(new FileInputStream(CSS));
        // cssResolver.addCss(cssFile);

        // HTML
        XMLWorkerFontProvider fontProvider = new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
        fontProvider.register("fonts/Arimo-Regular.ttf");
        fontProvider.register("fonts/Arimo-Bold.ttf");
        fontProvider.register("fonts/Arimo-Italic.ttf");
        fontProvider.addFontSubstitute("lowagie", "Arimo");
        CssAppliers cssAppliers = new CssAppliersImpl(fontProvider);
        HtmlPipelineContext htmlContext = new HtmlPipelineContext(cssAppliers);
        htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());

        // Pipelines
        PdfWriterPipeline pdf = new PdfWriterPipeline(document, writer);
        HtmlPipeline html = new HtmlPipeline(htmlContext, pdf);
        CssResolverPipeline css = new CssResolverPipeline(cssResolver, html);

        // XML Worker
        XMLWorker worker = new XMLWorker(css, true);
        XMLParser p = new XMLParser(worker);

        // p.parse(new FileInputStream(HTML));
        String htmlContent = " HERE GOES HTML CODE ";
        p.parse(new StringReader(htmlContent));
        // step 5
        document.close();
    }

    public static void main(String[] args) throws IOException, DocumentException {
        new D06_ParseHtmlFonts().createPdf(DEST);
    }
}


I noticed that it is important to have font-family: actual font that supports wished encoding;

in css / html and for email clients always use inline css.

Based on a comment from @ bruno-lowagie, only a small change to your posted code is required to get it working on Windows. For more information on how to specify a specific font, see the examples suggested by Bruno.



public class HTM {

    public static void main(String ... args ) {
        try {
            Document document = new Document(PageSize.LETTER);

            PdfWriter pdfWriter = PdfWriter.getInstance(document, new FileOutputStream("testpdf.pdf"));
            document.open();

            XMLWorkerHelper worker = XMLWorkerHelper.getInstance();

            String htmlString = "<html><head>"
                    + "<meta http-equiv=\"content-type\" content=\"application/xhtml+xml; charset=UTF-8\" />"
                    + "</head><body>"
                    + "<p style=\"font-family:courier new\">" // the font to use
                    + "<h1>Zdravo ј!</h1>"
                    + "</p>"
                    + "<h1>Zdravo ј!</h1>"
                    + "</body></html>";

            worker.parseXHtml(pdfWriter, document, new StringReader(htmlString));
            document.close();
            System.out.println("Done.");
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }
}
