Question

我有一个带法语口音的简单字符串。我想使用ITextRenderer将其保存到pdf。问题是所有重音都会从生成的pdf中删除。

要保存的输入字符串来自我的力度模板。在那里，我是doinf StringEscapeUtils.escape（StringEscapeUtils.unescape（stringWithAccents）），这个过程给我输入字符串，如Supplément：Visa＆amp; Pourboires“。

我的代码：

         String documentHtml = "Suppl&eacute;ment : &agrave;&egrave"
         DocumentBuilder builder;
        try {
            DocumentBuilderFactory fac = DocumentBuilderFactory.newInstance();
            fac.setFeature("http://xml.org/sax/features/namespaces", false);
            fac.setFeature("http://xml.org/sax/features/validation", false);
            fac.setFeature("http://apache.org/xml/features/nonvalidating/load-dtd-grammar", false);
            fac.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
            builder = fac.newDocumentBuilder();
            byte[] docByte = documentHtml.getBytes("UTF-8");
            ByteArrayInputStream is = new ByteArrayInputStream(docByte);
            Document doc = builder.parse(is);
            is.close();
            File file = new File(this.getFolder(), this.getFileName());
            if (file.exists()) {
                file.delete();
            }

            // save pdf
            OutputStream os = new FileOutputStream(file);
            ITextRenderer renderer = new ITextRenderer();
            renderer.setDocument(doc, file.getParentFile().getAbsolutePath());
            renderer.layout();
            renderer.createPDF(os, true);
            os.close();


            return this.getFolder().getAbsolutePath() + "/" + this.getFileName();
        } catch (ParserConfigurationException e) {
            LOGGER.error("Error while parsing the configuration " + e.getMessage(), e);
            throw new BOServiceException("Error while parsing the configuration : " + e.getMessage(), e);
        } catch (UnsupportedEncodingException e) {
            LOGGER.error("Encoding error :  " + e.getMessage(), e);
            throw new BOServiceException("Encoding error : " + e.getMessage(), e);
        } catch (SAXException e) {
            LOGGER.error("Error in the document because of SAX :  " + e.getMessage(), e);
            throw new BOServiceException("Error in the document because of SAX :  " + e.getMessage(), e);
        } catch (IOException e) {
            LOGGER.error("Error due to io problem : " + e.getMessage(), e);
            throw new BOServiceException("Error due to io problem :" + e.getMessage(), e);
        }

所以你知道为什么我的编码不起作用吗？为什么在结果pdf中我看不到像à＆amp; egrave

这样的字符

尝试将编码从UTF-8更改为ISO-8859-1。

java从带有重音符的字符串中保存pdf
