I’m working on converting HTML to PDF.

Do you know how to specify a default font when converting html to pdf using the Spire.doc for Java library? (Korean is broken)

// html to pdf
public static void pdfConvertorDefault(String inputHtml) throws IOException {
    // pdf 파일 생성
    Document document = new Document();
    document.setCustomFontsFolders("D:\font");
    Section section = document.addSection();
    section.getPageSetup().setPageSize(PageSize.A3);
    // Page 방향 (Landscape: 가로, Portrait : 세로)
    section.getPageSetup().setOrientation(PageOrientation.Landscape);

    String htmlText = readTextFromFile(inputHtml);  // inputHtml : "D:/test.html";
    
    document.setCustomFontsFolders("D:\font"); // Font Folder 지정
    //add a paragraph and append html string.
    Paragraph p = section.addParagraph();
    p.appendHTML(htmlText); // PDF Convertor
   
    //Save to PDF
    document.saveToFile("D://SpireDoc_ouput.pdf", FileFormat.PDF);
}

// htmlFile To String
public static String readTextFromFile(String fileName) throws IOException{
    StringBuffer sb = new StringBuffer();
    BufferedReader br = new BufferedReader(new FileReader(fileName));
    String content = null;
    while ((content = br.readLine()) != null) {
        sb.append(content);
    }
    return sb.toString();
}
