BaseFont unicode = null; unicode = BaseFont.createFont("D:/arialuni.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED); form.setGenerateAppearances(true); form.addSubstitutionFont(unicode); form.setField("TextBox","اب اب اب اب اب اب اب اب اب اب اب اب اب اب اب اب اب"); stamper.setFormFlattening(true); It's probably an encoding problem when you save, compile or execute your code (which means your problem is not related to iText).

Today I just can't get it to work. This is the old code, which uses FileStreams and it works: public static string OldPdfSigner(PdfReader pdfReader, string destination, string password, string reason, string location, string pathToPfx) { using (FileStream pfxFile = new FileStream(pathToPfx, FileMode.Open, FileAccess.Read)) { ... using (PdfStamper st = PdfStamper.CreateSignature(pdfReader, new FileStream
