我一直在努力使用FOP生成PDF，并使用波兰语字母。我一直在这里阅读很多帖子，但到目前为止还没有成功！
I've been struggling a lot with generating a PDF using FOP, with Polish letters. I have been reading a lot of posts here on SO but so far no success!
这是我的模板：
<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="www.w3/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"> <xsl:template match="root"> <fo:root xmlns:fo="www.w3/1999/XSL/Format"> <fo:layout-master-set> <fo:simple-page-master master-name="simpleA4" page-height="29.7cm" page-width="21cm" margin-top="2cm" margin-bottom="2cm" margin-left="2cm" margin-right="2cm"> <fo:region-body/> </fo:simple-page-master> </fo:layout-master-set> <fo:page-sequence master-reference="simpleA4"> <fo:flow flow-name="xsl-region-body"> <fo:block font-size="11pt" font-family='Arial'> <xsl:value-of select="TestString"/> </fo:block> </fo:flow> </fo:page-sequence> </fo:root> </xsl:template> </xsl:stylesheet>我的XML：
<?xml version="1.0" encoding="utf-8"?> <root> <TestString>Chcemy mieć pewność, że nasze produkty będą miały długą żywotność i stosujemy opakowania, aby uchronić je przed uszkodzeniem podczas przenoszenia i transportu.</TestString> </root>和我的Java代码调用它：
and my Java code calling it:
private void PolishTest() throws IOException, FOPException, TransformerException { // the XSL FO file File xsltFile = new File("C:\\Temp\\PolishTest.xsl"); // the XML file which provides the input StreamSource xmlSource = new StreamSource(new File("C:\\Temp\\PolishTest.xml")); // create an instance of fop factory FopFactory fopFactory = FopFactory.newInstance(new File(".").toURI()); // a user agent is needed for transformation FOUserAgent foUserAgent = fopFactory.newFOUserAgent(); // Setup output OutputStream out = new FileOutputStream("C:\\Temp\\PolishTest.pdf"); try { // Construct fop with desired output format Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out); // Setup XSLT TransformerFactory factory = TransformerFactory.newInstance(); Transformer transformer = factory.newTransformer(new StreamSource(xsltFile)); // Resulting SAX events (the generated FO) must be piped through to FOP Result res = new SAXResult(fop.getDefaultHandler()); // Start XSLT transformation and FOP processing // That's where the XML is first transformed to XSL-FO and then // PDF is created transformer.transform(xmlSource, res); } finally { out.close(); } }在我的模板中看到我使用Arial作为字体系列，如果我在单词中输入文字，使用Arial它可以很好地工作。但是当从Java调用它时
as seen in my template I'm using Arial as font family, and if I type the text in word, using Arial it works out very fine. But when calling it from Java
我收到很多警告：
jul. 10, 2018 8:16:57 AM org.apache.fop.events.LoggingEventListener processEvent WARNING: Font "Arial,normal,400" not found. Substituting with "any,normal,400". jul. 10, 2018 8:16:57 AM org.apache.fop.events.LoggingEventListener processEvent WARNING: Glyph "ć" (0x107, cacute) not available in font "Times-Roman". jul. 10, 2018 8:16:57 AM org.apache.fop.events.LoggingEventListener processEvent WARNING: Glyph "ś" (0x15b, sacute) not available in font "Times-Roman". jul. 10, 2018 8:16:57 AM org.apache.fop.events.LoggingEventListener processEvent WARNING: Glyph "ż" (0x17c, zdot) not available in font "Times-Roman". jul. 10, 2018 8:16:57 AM org.apache.fop.events.LoggingEventListener processEvent WARNING: Glyph "ę" (0x119, eogonek) not available in font "Times-Roman". jul. 10, 2018 8:16:57 AM org.apache.fop.events.LoggingEventListener processEvent WARNING: Glyph "ą" (0x105, aogonek) not available in font "Times-Roman". jul. 10, 2018 8:16:57 AM org.apache.fop.events.LoggingEventListener processEvent WARNING: Glyph "ł" (0x142, lslash) not available in font "Times-Roman". jul. 10, 2018 8:16:57 AM org.apache.fop.events.LoggingEventListener processEvent所以我的问题是（因为）我做错了什么？
So my question is (ofcause) what am I doing wrong?
FOP如何选择Times-Roman，即使我已经指定了Arial？更重要的是如何解决它？
How come FOP chooses "Times-Roman", even though I've specified Arial? And more important how to fix it?
**更新**
使用am9417答案的代码我已将我的Java代码更新为以下：
With the code from am9417's answer I've updated my Java code to the following:
private static String config = "<?xml version=\"1.0\" encoding=\"utf-8\" ?>\n" + "<fop>\n" + " <renderers>\n" + " <renderer mime=\"application/pdf\">\n" + " <fonts>\n" + " <auto-detect/>\n" + " </fonts>\n" + " </renderer>\n" + " </renderers>\n" + "</fop>"; private void PolishTest() throws IOException, SAXException, TransformerException { // the XSL FO file File xsltFile = new File("C:\\Temp\\PolishTest.xsl"); // the XML file which provides the input StreamSource xmlSource = new StreamSource(new File("C:\\Temp\\PolishTest.xml")); // create an instance of fop factory URI uri = new File(".").toURI(); InputStream configSource = new ByteArrayInputStream(config.getBytes()); FopFactory fopFactory = FopFactory.newInstance(uri, configSource); // a user agent is needed for transformation FOUserAgent foUserAgent = fopFactory.newFOUserAgent(); // Setup output OutputStream out = new FileOutputStream("C:\\Temp\\PolishTest.pdf"); try { // Construct fop with desired output format Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out); // Setup XSLT TransformerFactory factory = TransformerFactory.newInstance(); Transformer transformer = factory.newTransformer(new StreamSource(xsltFile)); // Resulting SAX events (the generated FO) must be piped through to FOP Result res = new SAXResult(fop.getDefaultHandler()); // Start XSLT transformation and FOP processing // That's where the XML is first transformed to XSL-FO and then // PDF is created transformer.transform(xmlSource, res); } finally { out.close(); } }推荐答案
此答案可能包含一些有用的信息。所有错误都是由于找不到Arial字体引起的，这就是为什么它切换到Times-Roman，因为无法找到特殊字符（由于某种原因）。
This answer might contain some useful information. All the errors are caused because Arial font is not found, that's why it switches to Times-Roman where special characters (for some reason) cannot be found.
所以，如同在该答案中，为FOP添加具有以下内容的配置xml以引用系统中的Arial字体：
So, as in that answer, add the config xml for the FOP with the following content to refer to the Arial font in your system:
C：\ Temp \ fopconf.xml
<?xml version="1.0" encoding="utf-8" ?> <fop> <renderers> <renderer mime="application/pdf"> <fonts> <font kerning="yes" embed-url="file:///C:/windows/fonts/arial.ttf"> <font-triplet name="Arial" style="normal" weight="normal"/> </font> </fonts> </renderer> </renderers> </fop>使用文件 object：
Add the reference to that config file in the FopFactory constructor with a File object:
// create an instance of fop factory FopFactory fopFactory = FopFactory.newInstance(new File("C:\\Temp\\fopconf.xml"));现在文件应该呈现并且字体应该是正确的：
Now the file should render and the font should be correct:
C：\ Temp \ PolishTest.pdf
编辑： 进一步测试后，我很幸运< auto-detect /> ; 标签。但是，在尝试搜索字体时，渲染需要花费更多时间。如果您不知道字体文件位置，这可能很有用。您可能想尝试一下：
After testing this further, I had luck with <auto-detect /> tag. However, rendering took a bit more time when it tried to search the fonts. This might be useful if you don't know the font file location. You might want to give it a try:
... <fonts> <auto-detect/> </fonts> ...
