html to pdf转换，西里尔字符不能正常显示 [英] html to pdf convert, cyrillic characters not displayed properly
问题描述
我的pdf字体有问题。我使用了一种从html生成pdf的方法，在本地机器上运行正常，这是Windows操作系统，但现在在linux上，西里尔文本显示有问号。我检查了那里的字体，但事实证明，需要字体。现在我转到另一种方法，如下所示。
I have a problem with pdf fonts. I have used a method for generating pdf from html which worked fine on my local machine which is windows OS, but now on linux Cyrillic text is displayed with question marks. I checked for fonts there but it turned out that there were required fonts. Now I switched to another method which is shown below.
Document document = new Document(PageSize.A4);
String myFontsDir = "C:\\";
String filePath = AppProperties.downloadLocation + "Order_" + orderID + ".pdf";
try {
OutputStream file = new FileOutputStream(new File(filePath));
PdfWriter writer = PdfWriter.getInstance(document, file);
int iResult = FontFactory.registerDirectory(myFontsDir);
if (iResult == 0) {
System.out.println("TestPDF(): Could not register font directory " + myFontsDir);
} else {
System.out.println("TestPDF(): Registered font directory " + myFontsDir);
}
document.open();
String htmlContent = "<html><head>"
+ "<meta http-equiv=\"content-type\" content=\"application/xhtml+xml; charset=UTF-8\"/>"
+ "</head>"
+ "<body>"
+ "<h4 style=\"font-family: arialuni, arial; font-size:16px; font-weight: normal; \" >"
+ "Здраво Kristijan!"
+ "</h4></body></html>";
InputStream inf = new ByteArrayInputStream(htmlContent.getBytes("UTF-8"));
XMLWorkerFontProvider fontImp = new XMLWorkerFontProvider(myFontsDir);
FontFactory.setFontImp(fontImp);
XMLWorkerHelper.getInstance().parseXHtml(writer, document, inf, null, null, fontImp);
document.close();
System.out.println("Done.");
} catch (Exception e) {
e.printStackTrace();
}
这个平安的代码我能够从拉丁文本生成正确的pdf，但西里尔字体与奇怪的字符一起显示。这在Windows上发生，我还没有在Linux上测试。任何编码或字体的建议？
with this peace of code I am able to generate proper pdf from latin text, but cyrillic is displayed with weird characters. This happens on Windows, I haven't yet test it on Linux. Any advice for encoding or font?
提前感谢
推荐答案
首先，很难相信您的字体目录是 C：\\ 。你假设你有一个路径 C：\\\arialuni.ttf 的文件，而我认为MS Arial Unicode的路径是 C ：\\windows\fonts\arialuni.ttf 。
First this: it is very hard to believe that your font directory is C:\\. You are assuming that you have a file with path C:\\arialuni.ttf whereas I assume that the path to MS Arial Unicode is C:\\windows\fonts\arialuni.ttf.
其次：我不认为 arialuni 是正确的名称。我确定它是 arial unicode ms 。您可以通过运行以下代码来检查此代码：
Secondly: I don't think arialuni is the correct name. I'm pretty sure it's arial unicode ms. You can check this by running this code:
XMLWorkerFontProvider fontProvider = new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
fontProvider.register("c:/windows/fonts/arialuni.ttf");
for (String s : fontProvider.getRegisteredFamilies()) {
System.out.println(s);
}
输出应为：
courier
arial unicode ms
zapfdingbats
symbol
helvetica
times
times-roman
这些是你可以使用的值; arialuni 不是其中之一。
These are the values you can use; arialuni isn't one of them.
另外：你不是在错误的地方定义字符集？
Also: aren't you defining the character set in the wrong place?
我稍微调整了您的源代码，因为我将HTML存储在HTML文件中 cyrillic.html ：
I have slightly adapted your source code in the sense that I stored the HTML in an HTML file cyrillic.html:
<html>
<head>
<meta http-equiv="content-type" content="application/xhtml+xml; charset=UTF-8"/>
</head>
<body>
<h4 style="font-family: Arial Unicode MS, FreeSans; font-size:16px; font-weight: normal; " >Здраво Kristijan!</h4>
</body>
</html>
请注意，我将 arialuni 替换为 Arial Unicode MS ，我使用 FreeSans 作为替代字体。在我的代码中，我使用 FreeSans.ttf 而不是 arialttf 。
Note that I replaced arialuni with Arial Unicode MS and that I used FreeSans as an alternative font. In my code, I used FreeSans.ttf instead of arialttf.
请参阅 ParseHtml11 ：
public static final String DEST = "results/xmlworker/cyrillic.pdf";
public static final String HTML = "resources/xml/cyrillic.html";
public static final String FONT = "resources/fonts/FreeSans.ttf";
public void createPdf(String file) throws IOException, DocumentException {
// step 1
Document document = new Document();
// step 2
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
// step 3
document.open();
// step 4
XMLWorkerFontProvider fontImp = new XMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
fontImp.register(FONT);
FontFactory.setFontImp(fontImp);
XMLWorkerHelper.getInstance().parseXHtml(writer, document,
new FileInputStream(HTML), null, Charset.forName("UTF-8"), fontImp);
// step 5
document.close();
}
如您所见，我使用 Charset 解析HTML。结果如下：
As you can see, I use the Charset when parsing the HTML. The result looks like this:
如果您坚持使用Arial Unicode，只需替换此行：
If you insist on using Arial Unicode, just replace this line:
public static final String FONT = "resources/fonts/FreeSans.ttf";
使用这一个：
public static final String FONT = "c:/windows/fonts/arialuni.ttf";
我已经在Windows机器上测试过，它也可以工作：
I have tested this on a Windows machine and it works too:
