问题描述

我是 iText 库的新手.我有一个要求，我需要将输出提供为 PDF.pdf中有阿拉伯字符.我创建了一个如下所示的测试 servlet.

I am new to iText library. I have a requirement where i need to provide the output as PDF. The pdf has Arabic characters in it. I created a test servlet as given below.

 public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

response.setContentType ("application/pdf;charset=UTF-8");
Document document = new Document();
    try{
        PdfWriter.getInstance(document, 
            response.getOutputStream()); // Code 2
        document.open();

        Font f1;
  BaseFont bf  = BaseFont.createFont("C:\\WINDOWS\\Fonts\\ARIALUNI.ttf", BaseFont.CP1252, true);
  f1 = new Font(bf, 10);

        PdfPTable table = new PdfPTable(2);
        table.addCell("hellooooo1");
        table.addCell("world2");
        table.addCell("1113");
        table.addCell("422");

 // String a = "يبسبيبيبيسسسيبيببيسبيسيببي";
  String a = "سش";
  PdfPCell cell = new PdfPCell (new Paragraph (a,f1));
  table.addCell (cell);
  cell = new PdfPCell (new Paragraph ("Road",f1));
  table.addCell (cell);

        document.add(table);        
        document.close(); 
    }catch(DocumentException e){
        e.printStackTrace();
    }
}

我们使用阿拉伯字符的输出显示为 ?????.如何纠正这个问题?我在哪里犯了错误?

The out put where we use the arabic characters are being displayed as ????? . How to rectify this problem? where i am making the mistake?

推荐答案

您的问题是您正在使用 Windows CP1252 字符集创建 BaseFont，该字符集仅适用于拉丁字符.尝试使用 Unicode 编码:

Your problem is where you're creating the BaseFont with the Windows CP1252 Character Set, which is only suitable for latin characters. Try the encoding for Unicode instead:

 BaseFont bf  = BaseFont.createFont("C:\\WINDOWS\\Fonts\\ARIALUNI.ttf", BaseFont.IDENTITY_H, true);
