Itext阿拉伯字体作为问号

问题描述

我是iText图书馆的新手。我有一个要求，我需要提供PDF格式的输出。 pdf中包含阿拉伯字符。我创建了一个测试servlet，如下所示。

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正在显示为????? 。
如何纠正这个问题？我在哪里弄错了？

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

您的问题在于您使用Windows CP1252字符集创建BaseFont，该字符集仅适用于拉丁字符。请尝试编码Unicode：

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);
