Question

我正在尝试使用iTextSharp在PDF中显示“✔”字符。但是，角色不会显示在创建的PDF上。请帮帮我。

Answer 1

Phrase phrase = new Phrase("A check mark: ");   
Font zapfdingbats = new Font(Font.FontFamily.ZAPFDINGBATS);
phrase.Add(new Chunk("\u0033", zapfdingbats));
phrase.Add(" and more text");
document.Add(phrase);

Answer 2

Font Wingdings打印此字符而不是“o”。您需要将此字体连接到您的应用程序，然后将此字体应用于字母并将字体嵌入到pdf中以实现兼容性。

这是我之前在我的一个项目中使用的功能（未清理）。请清理它，但它有一些你需要的基本功能。（我将自定义字体（font1.ttf和font2.ttf）复制到项目目录中）

我希望它会对你有所帮助。

    public void StartConvert(String originalFile, String newFile)
    {
        Document myDocument = new Document(PageSize.LETTER);
        PdfWriter.GetInstance(myDocument, new FileStream(newFile, FileMode.Create));
        myDocument.Open();

        int totalfonts = FontFactory.RegisterDirectory("C:\\WINDOWS\\Fonts");
        iTextSharp.text.Font content = FontFactory.GetFont("Pea Heather's Handwriting", 13);//13
        iTextSharp.text.Font header = FontFactory.GetFont("assign", 16); //16

        BaseFont customfont = BaseFont.CreateFont(@"font1.ttf", BaseFont.CP1252, BaseFont.EMBEDDED);
        Font font = new Font(customfont, 13);
        string s = " ";
        myDocument.Add(new Paragraph(s, font));

        BaseFont customfont2 = BaseFont.CreateFont(@"font2.ttf", BaseFont.CP1252, BaseFont.EMBEDDED);
        Font font2 = new Font(customfont2, 16);
        string s2 = " ";
        myDocument.Add(new Paragraph(s2, font2));

        try
        {
            try
            {                   
                using (StreamReader sr = new StreamReader(originalFile))
                {
                    // Read and display lines from the file until the end of
                    // the file is reached.
                    String line;
                    while ((line = sr.ReadLine()) != null)
                    {
                        String newTempLine = "";
                        String[] textArray;
                        textArray = line.Split(' ');
                        newTempLine = returnSpaces(RandomNumber(0, 6)) + newTempLine;

                        int counterMax = RandomNumber(8, 12);
                        int counter = 0;
                        foreach (String S in textArray)
                        {
                            if (counter == counterMax)
                            {
                                Paragraph P = new Paragraph(newTempLine + Environment.NewLine, font);
                                P.Alignment = Element.ALIGN_LEFT;
                                myDocument.Add(P);
                                newTempLine = "";
                                newTempLine = returnSpaces(RandomNumber(0, 6)) + newTempLine;
                            }
                            newTempLine = newTempLine + returnSpaces(RandomNumber(1, 5)) + S;
                            counter++;
                        }
                        Paragraph T = new Paragraph(newTempLine, font2);
                        T.Alignment = Element.ALIGN_LEFT;

                        myDocument.Add(T);
                    }
                }
            }
            catch (Exception e)
            {
                Console.WriteLine("The file could not be read:");
                Console.WriteLine(e.Message);
            }
        }
        catch (DocumentException de)
        {
            Console.Error.WriteLine(de.Message);
        }
        catch (IOException ioe)
        {
            Console.Error.WriteLine(ioe.Message);
        }

        try
        {
            myDocument.Close();
        }
        catch { }
    }
