我正在将iText与Java一起使用，我想打印大于或等于（≥），但是当您检查pdf时它将打印空白。字体：
public static final String FONT_A1L = "/opt/efact/ose/pdf/v1.0.0/conf/resources/fonts/ARIALUNI.TTF";
输入是包含符号的字符串：
String text = "Item (≥110)";
或
String text = "Item (\u2265 110)";
它已正确存储在包含符号≥的变量中，因此在pdf中打印时会出现问题。我正在使用PdfTable：
PdfPTable documentDetail = new PdfPTable(1);
documentDetail.setWidths(new float[] {800});
documentDetail.setTotalWidth(800);
documentDetail.setLockedWidth(true);
documentDetail.addCell(createPDFPCellBorder(true, true, true, false, BaseColor.LIGHT_GRAY, generalBaseColorFont, boldGrayFont10, Rectangle.BOTTOM, IPDFConstants.HEIGHT_FIXED, heightSize, new Integer[][]{ {IPDFConstants.PADDING_TOP,-2}, {IPDFConstants.PADDING_BOTTOM, 5}},
text, com.itextpdf.text.Element.ALIGN_CENTER, com.itextpdf.text.Element.ALIGN_CENTER, com.itextpdf.text.Element.ALIGN_RIGHT, null));
documentDetail.writeSelectedRows(0, -1, 50, getHeight(50), canvas);
当我运行程序并检查pdf时，将写入以下内容： 项目（110）
颜色创建为（类本身在帖子的底部）：
BaseColor generalBaseColorFont = new BaseColor(new Color(173, 173, 173));
如何打印此类字符？
如果可能有用，这是我正在使用的过程的代码（我自己没有编写此代码，这是工作的结果）：
