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：
