Itext 阿拉伯字体以问号形式出现
我是 iText 库的新手。我有一个要求，我需要提供 PDF 格式的输出。 pdf 中有阿拉伯字符。我创建了一个测试 servlet，如下所示。
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？
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){

您的问题是您使用 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:
