When you convert a word file to PDF, the Chinese characters in the word file will be broken and converted. I need help.
test.docx (5.8 MB)

java code

String wordFilePath = "D:" + File.separator + "test.docx";
String pdfFilePath = "D:" + File.separator + "test.pdf";
Document pdf = new Document(wordFilePath);


FontSettings fontSettings = new FontSettings();
String fontsDir = "C:\\Windows\\Fonts";
fontSettings.setFontsFolder(fontsDir, true);
pdf.setFontSettings(fontSettings);

PdfSaveOptions saveOptions = new PdfSaveOptions();
saveOptions.setEmbedFullFonts(true); 
saveOptions.setUseCoreFonts(true);
saveOptions.setSaveFormat(SaveFormat.PDF);

pdf.save(pdfFilePath, saveOptions);

@3pchain Could you please also attach your output document here for our reference? I have checked conversion on my side and do not see broken characters in the output.
Also, 'HY견고딕' font used in your document is not available on my side. Could you please attach this font too.
