提问by Estev?o Jord?o

I am using iText to generate some PDFs, these pdfs have some Chinese characters (Simplified Chinese - GB2312), however I am unable to generate a pdf with these characters.

我正在使用 iText 生成一些 PDF，这些 pdf 有一些中文字符（简体中文 - GB2312），但是我无法生成带有这些字符的 pdf。

Anyone could tell me where I am wrong?

谁能告诉我我错在哪里？

I tried using various forms of creation but did not succeed:

我尝试使用各种形式的创作但没有成功：

BaseFont bf = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED); 


com.itextpdf.text.DocumentException: Font 'STSong-Light' with 'UniGB-UCS2-H' is not recognized.

BaseFont bfComic = BaseFont.createFont(AsianFontMapper.ChineseSimplifiedFont,  AsianFontMapper.ChineseSimplifiedEncoding_H, BaseFont.NOT_EMBEDDED);
       Font fontbold = new Font(bfComic, 8);


 BaseFont bfComic = BaseFont.createFont("C:\Windows\Fonts\cour.ttf",  BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
       Font fontbold = new Font(bfComic, 8);

Could someone help me?

有人可以帮助我吗？

Adding question, this is my current code for testing:

添加问题，这是我当前的测试代码：

while(null != (line = reader.readLine())) {
    document.open();

    FontSelector selector = new FontSelector();
    /*FontFactory.getFont("MSung-Light","UniCNS-UCS2-H", BaseFont.NOT_EMBEDDED);*/
    Font f2 = FontFactory.getFont(AsianFontMapper.ChineseSimplifiedFont, AsianFontMapper.ChineseTraditionalEncoding_H, BaseFont.NOT_EMBEDDED);
    f2.setColor(BaseColor.RED);
    selector.addFont(f2);
    Phrase ph = selector.process(line);
    document.add(new Paragraph(ph));


    BaseFont bfComic = BaseFont.createFont("C:\Windows\Fonts\arialuni.ttf",  BaseFont.IDENTITY_V, BaseFont.EMBEDDED);
    Font fontbold = new Font(bfComic, 8);
    Paragraph p = new Paragraph(line, fontbold);
    document.add(p);

    // step 5: we close the document
}

You have the iText jar in your CLASSPATH, but you forgot to add the (correct) itext-asian.jar.

您的 CLASSPATH 中有 iText jar，但您忘记添加（正确的）itext-asian.jar。

Please download version 2.3 of the extra jars ZIP-file that is available here: http://sourceforge.net/projects/itext/files/extrajars/

请下载 2.3 版的额外 jars ZIP 文件，可在此处获得：http: //sourceforge.net/projects/itext/files/extrajars/

This jar contains metrics for Chinese glyphs. Such a font will never be embedded. When you open a document using such a font in Adobe Reader, you may be asked to install an extra font pack.

这个 jar 包含中国字形的度量。这种字体永远不会被嵌入。当您在 Adob​​e Reader 中使用此类字体打开文档时，可能会要求您安装额外的字体包。

The solution adopted:

采用的解决方案：

private static final String PATH_FONT_ARIALUNI = "C:\Windows\Fonts\arialuni.ttf";
      private static final String PATH_FONT_COUR = "C:\Windows\Fonts\cour.ttf";



       // FOR Chinese
       BaseFont baseFont = BaseFont.createFont(PATH_FONT_ARIALUNI, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
       Font font = new Font(baseFont, 6.8f);

       BaseFont baseFontNormal = BaseFont.createFont(PATH_FONT_COUR, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
       Font fontNormal = new Font(baseFontNormal, 6.8f);

       Paragraph par = new Paragraph();
       par.setLeading(9);

       char[] aa = line.toCharArray();
       boolean isLastChineseChar = false;

       System.out.println(line);

       StringBuilder newLine = new StringBuilder();
       for (int j = 0; j < line.length(); j++) {

           if((Character.UnicodeBlock.of(aa[j]) == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS)){
               if(!isLastChineseChar) {
                   par.add(new Phrase(newLine.toString(), fontNormal));
                   newLine.delete(0, newLine.length());
               }
               newLine.append(aa[j]);
               isLastChineseChar = true;
               /*System.out.println("Is CHINESE: " + aa[j]);*/
           } else {
               if(isLastChineseChar) {
                   par.add(new Phrase(newLine.toString(), font));
                   newLine.delete(0, newLine.length());
                   isLastChineseChar = false;
               }
               newLine.append(aa[j]);
               /*System.out.println("NOT IS CHINESE: " + aa[j]);*/
           }
       }

       if(isLastChineseChar){
           par.add(new Phrase(newLine.toString(), font));
       } else {
           par.add(new Phrase(newLine.toString(), fontNormal));
       }       

       if(line.contains(BREAK_PAGE)) {
          document.newPage();
       }

       par.setAlignment(Element.ALIGN_LEFT);
       document.add(par);
