将阿拉伯语内容添加到PDF格式的表格中

Answer 1

过去的回答可以帮到你： How to display Arabic in PDF created using iText

这个答案建议使用unicode值而不是在代码中直接输入阿拉伯语，因为这样做是不好的做法。确保您从不在源代码中使用非西方文本：

  

使用UNICODE表示法：“\ u0627 \ u0644 \ u0645 \ u0648 \ u0642 \ u0646 \ u0644 \ u0625 \ u0644 \ u062a \ u0632 \ u0648 \ u0646 \ u064a \ u064a”

以下是来自this网站的示例代码，您可以看到如何使用UNICODE表示法完成此操作：

import java.io.FileOutputStream;

import com.lowagie.text.Document;
import com.lowagie.text.PageSize;
import com.lowagie.text.pdf.PdfContentByte;
import com.lowagie.text.pdf.PdfWriter;

public class ArabicTextPDF {
  public static void main(String[] args) {
    Document document = new Document(PageSize.A4, 50, 50, 50, 50);
    try {
      PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("ArabicTextPDF.pdf"));
      document.open();
      java.awt.Font font = new java.awt.Font("arial", 0, 18);
      PdfContentByte cb = writer.getDirectContent();
      java.awt.Graphics2D g2 = cb.createGraphicsShapes(PageSize.A4.width(), PageSize.A4.height());
      g2.setFont(font);
      g2.drawString("\u0634\u0627\u062f\u062c\u0645\u0647\u0648\u0645\u0646", 100, 100);
      g2.dispose();
      document.close();
    } catch (Exception de) {
      de.printStackTrace();
    }
  }
}

另外，正如建议的那样，另一种解决方案可能是使用arialuni.ttf：

  

您假设arialbd.ttf可以生成阿拉伯字形。据我所知，只有arialuni.ttf支持阿拉伯语。

您应该注意，最新的Windows升级不再附带arialuni.ttf，因此@Bruno Lowagie建议，您可以用NOTO字体替换.ttf文件（Google提供的免费字体）支持阿拉伯语。您可以了解有关NOTO字体here的更多信息。

如果这可以解决您的问题，请告诉我，否则我会尽力帮助您。
