Itext Html to PDF Arabic text broken

Question

When i am converting html to pdf in C# the arabic text is broken and also seems to be reversed. I have tried direction rtl, adding arabic fonts.

.arabic { direction: rtl; unicode-bidi: isolate; font-family: 'NotoNaskhArabic', sans-serif; } @@font-face { font-family: 'NotoNaskhArabic'; src: url('C:/Users/fahad.a/Downloads/NotoNaskhArabic-Regular.ttf') format('truetype'); } <td class="tdh" style="font-family: 'NotoNaskhArabic', sans-serif;">Date<span class="arabic" id="arabic" style="display:none; direction: rtl !important; font-family: 'NotoNaskhArabic', sans-serif;"><br>تاريخ الطلب</span></td>

ConverterProperties properties = new ConverterProperties();

FontProvider fontProvider = new FontProvider(); fontProvider.AddStandardPdfFonts();

fontProvider.AddFont("C:/Users/fahad.a/Downloads/NotoNaskhArabic-Regular.ttf"); // Ensure the path is correct fontProvider.AddFont("C:/Users/fahad.a/Downloads/NotoKufiArabic-Regular.ttf"); // For bold text, if needed properties.SetFontProvider(fontProvider); properties.SetCharset("UTF-8"); // Ensure UTF-8 charset to handle Arabic script

// Add default styles properties.SetCssApplierFactory(new DefaultCssApplierFactory());

iText.Kernel.Pdf.PdfWriter writer = new iText.Kernel.Pdf.PdfWriter(destination, new WriterProperties().SetFullCompressionMode(true)); iText.Kernel.Pdf.PdfDocument pdfDocument = new iText.Kernel.Pdf.PdfDocument(writer);

//iText.Kernel.Font.PdfFont f = PdfFontFactory.CreateFont("/fonts/NotoSansMyanmar-Regular.ttf", PdfEncodings.IDENTITY_H, true);

HtmlConverter.ConvertToPdf(htmltrimmed, pdfDocument, properties);

pdfDocument.Close();

you also need to install itext.pdfcalligraph that is listed on your screenshot (this add-on is not dual licensed, like itext core, or pdfhtml). — André Lemos

with pdfCalligraph loaded, then things should work automagically. there's no special API that needs to get used. You can get a trial license to see if it works for you. — André Lemos

when using the following iText code to convert from HTML to PDF I get the exepected result:

 LicenseKey.LoadLicenseFile(new FileInfo("licensefile.json")); using (FileStream htmlSource = File.Open("input.html", FileMode.Open)) using (FileStream pdfDest = File.Open("output.pdf", FileMode.Create)) { ConverterProperties properties = new ConverterProperties(); FontProvider fontProvider = new FontProvider(); fontProvider.AddStandardPdfFonts(); fontProvider.AddFont("NotoNaskhArabic-Regular.ttf"); properties.SetFontProvider(fontProvider); properties.SetCharset("UTF-8"); HtmlConverter.ConvertToPdf(htmlSource, pdfDest, properties); }

It is important that you also load the pdfCalligraph Add On and that it is included in your license. The C# project file should contain at least:

 <ItemGroup> <PackageReference Include="itext7" Version="8.0.4" /> <PackageReference Include="itext7.bouncy-castle-adapter" Version="8.0.4" /> <PackageReference Include="itext.licensing.base" Version="4.1.4" /> <PackageReference Include="itext.licensing.remote" Version="4.1.4" /> <PackageReference Include="itext7.pdfcalligraph" Version="4.0.2" /> <PackageReference Include="itext7.pdfhtml" Version="5.0.4" /> </ItemGroup>

For testing, I use the following sample HTML (input.html`)

<html> <style> .rabic { direction: rtl; unicode-bidi: isolate; font-family: 'NotoNaskhArabic', sans-serif; } @font-face { font-family: 'NotoNaskhArabic'; src: url('NotoNaskhArabic-Regular.ttf') format('truetype'); } </style> <body> <div style="font-family: 'NotoNaskhArabic', sans-serif;">Date<span class="arabic" id="arabic" style="direction: rtl !important; font-family: 'NotoNaskhArabic', sans-serif;"><br>تاريخ الطلب</span></div> </body> </html>

And the result is:

hope this helps.
