关于PDFBox读取Identity-H编码的乱码问题，附pdf
软件版本：pdfbox-0.8.0-incubating
PDF转换软件：Adobe Acrobat6.0,Foxit PDF Creator
问题描述：用比较专业的Foxit PDF Creator转换没有问题，用Acrobat转换时，转换出的pdf可以正常用Adobe Reader打开，但是用pdfbox打开出现乱码。
转换方法，打开word文件，选择打印，选择打印机如图
转换后可以看到pdf的字体有所不同，是Identity－H
而用Foxit转换出来的正常可以读取的pdf文件字体应该是UniGB-USC2-H
所以字体应该出现在字体编码上，不知道有没有解决方案。运行结果如下：
解析pdf的源码如下：
?
public void testPDF() {try {String ts = GetTextFromPdf("c:\\temp\\test.pdf");System.out.println(ts);} catch (Exception e) {e.printStackTrace();}}public String GetTextFromPdf(String filename) throws Exception {String temp = null;PDDocument pdfdocument = null;FileInputStream is = new FileInputStream(filename);PDFParser parser = new PDFParser(is);parser.parse();pdfdocument = parser.getPDDocument();PDFTextStripper ts = new PDFTextStripper();String content = ts.getText(pdfdocument);return content;}?附件中有word文件和异常的pdf文件。
× 建议用其他包转换的勿复

今天下载了1.1.0版本，惊喜的发现，不仅解决了UniGB-UCS2-H问题，而且Identity-H编码的问题也得到解决了，还解决了以前一个不大不小的bug，容易在文字中出现空格，到底是官方升级的好阿，比自己杂七杂八揍了一堆补丁要舒服多了。顺利通过了自己的十来个测试样本，只有一个嵌入字体的pdf出现问题，异常如下：
