Docx 到 Pdf 替換字符

Question

我有一個包含漢字和其他亞洲語言的 docx 文件。 我可以在筆記本電腦上將 docx 文件完美地轉換為 PDF 文件，中文字符正確嵌入到 PDF 中，但是當相同的代碼在 Linux 服務器上作為可運行的 jar 運行時，中文字符被替換為 # 符號。 有人可以指導我解決這個問題嗎？ 提前感謝您的幫助。 下面給出了java代碼

public static void main(String[] args) throws Exception {

    try {

        Docx4jProperties.getProperties().setProperty("docx4j.Log4j.Configurator.disabled", "true");
        Log4jConfigurator.configure();
        org.docx4j.convert.out.pdf.viaXSLFO.Conversion.log.setLevel(Level.OFF);

        System.out.println("Getting input Docx File");
        InputStream is = new FileInputStream(new File(
                "C:/Users/nithins/Documents/plugin docx to pdf/other documents/Contains Complex Fonts Verified.docx"));
        WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(is);
        wordMLPackage.setFontMapper(new IdentityPlusMapper());

        System.out.println("Setting File Encoding");
        System.setProperty("file.encoding", "Identity-H");
        System.out.println("Generating PDF file");

        org.docx4j.convert.out.pdf.PdfConversion c = new org.docx4j.convert.out.pdf.viaXSLFO.Conversion(
                wordMLPackage);
        File outFile = new File(
                "C:/Users/nithins/Documents/plugin docx to pdf/other documents/Contains Complex Fonts Verified.pdf");
        OutputStream os = new FileOutputStream(outFile);
        c.output(os, new PdfSettings());
        os.close();

        System.out.println("Output pdf file generated");
    } catch (Exception e) {
        e.printStackTrace();
    }

}

public static String changeExtensionToPdf(String path) {
    int markerIndex = path.lastIndexOf(".docx");
    String pdfFile = path.substring(0, markerIndex) + ".pdf";
    return pdfFile;
}

復制自 docx4j 的“入門”文檔：

docx4j can only use fonts which are available to it.

These fonts come from 2 sources:
•   those installed on the computer
•   those embedded in the document

Note that Word silently performs font substitution.  When you open an existing document in 
Word, and select text in a particular font, the actual font you see on the screen won't be 
the font reported in the ribbon if it is not installed on your computer or embedded in the 
document.  To see whether Word 2007 is substituting a font, go into Word Options 
> Advanced > Show Document Content and press the "Font Substitution" button.  

Word's font substitution information is not available to docx4j.  As a developer, you 3 
options:
•   ensure the font is installed or embedded
•   tell docx4j which font to use instead, or
•   allow docx4j to fallback to a default font

To embed a font in a document, open it in Word on a computer which has the font installed 
(check no substitution is occuring), and go to Word Options > Save > Embed Fonts in File.

If you want to tell docx4j to use a different font, you need to add a font mapping.  The 
FontMapper interface is used to do this.

On a Windows computer, font names for installed fonts are mapped 1:1 to the corresponding 
physical fonts via the IdentityPlusMapper. 

A font mapper contains Map<String, PhysicalFont>; to add a font mapping, as per the example in the ConvertOutPDF sample:
    // Set up font mapper
    Mapper fontMapper = new IdentityPlusMapper();
    wordMLPackage.setFontMapper(fontMapper);

    // .. example of mapping font Times New Roman which doesn't have certain Arabic glyphs
    // eg Glyph "ي" (0x64a, afii57450) not available in font "TimesNewRomanPS-ItalicMT".
    // eg Glyph "ج" (0x62c, afii57420) not available in font "TimesNewRomanPS-ItalicMT".
    // to a font which does
    PhysicalFont font 
            = PhysicalFonts.get("Arial Unicode MS"); 
        // make sure this is in your regex (if any)!!!
    if (font!=null) {
        fontMapper.put("Times New Roman", font);
        fontMapper.put("Arial", font);
    }

You'll see the font names if you configure log4j debug level logging for
 org.docx4j.fonts.PhysicalFonts

如果您打開 org.docx4j.fonts 的登錄，它應該會告訴您缺少的字形。 見https://github.com/plutext/docx4j/blob/master/src/main/java/org/docx4j/fonts/GlyphCheck.java
