我创建了一个PDF表单，然后使用PDFStamper和iText 2.1.4填写字段 . 当字段中包含国际字符时，生成的PDF中的字符看起来很奇怪 . 我检查了输出文件，国际字符看起来很好，所以我假设它是某种字体问题 .

我已经包含了填充PDF证书的屏幕截图以及看起来很滑稽的字符（正确的名称是GÓMEZORTÍZ） .

这是我正在使用的Java代码：

import java.io.*;
import java.util.*;

import com.lowagie.text.DocumentException;
import com.lowagie.text.pdf.AcroFields;
import com.lowagie.text.pdf.PdfReader;
import com.lowagie.text.pdf.PdfStamper;

class Field 
  {
  public String key;
  public String value;

  public Field(String key, String value) 
    {
    this.key = key;
    this.value = value;
    }
  }

public class PdfCertificate 
  {
  public static void main(String[] args)
    throws IOException, DocumentException
    {
    String input_file = args[0];
    String field_file = args[1];
    String output_file = args[2];

    FileInputStream fstream = new FileInputStream(field_file);

    BufferedReader bstream = new BufferedReader(new InputStreamReader(fstream));

    String line;
    Vector vector = new Vector();

    while ((line = bstream.readLine()) != null)   
      {
      int comma = line.indexOf(',');
      String key = line.substring(0, comma).trim();
      String value = line.substring(comma + 1, line.length()).trim();
      System.out.println(key + " => " + value);
      Field field = new Field(key, value);
      vector.add(field);
      }

    dstream.close();

    PdfReader reader = new PdfReader(input_file);

    FileOutputStream output_stream = new FileOutputStream(output_file); 
    PdfStamper stamper = new PdfStamper(reader, output_stream); 
    AcroFields form = stamper.getAcroFields();

    for (int i = 0; i < vector.size(); i++)
      {
      Field field = (Field) vector.elementAt(i);
      form.setField(field.key, field.value);
      }

    stamper.setFormFlattening(true);
    stamper.close();
    }
  }

干杯，格雷厄姆
