Describe the bug the library doesn't support Chinese

To Reproduce Code snippet to reproduce the behavior:

String content = "中国";
final pdf = pw.Document();
    pdf.addPage(pw.Page(
        pageFormat: PdfPageFormat.a4,
        build: (pw.Context context) {
          return pw.Center(
            child: pw.Text(content),
          ); // Center
        }));
    final dirPath = (await getApplicationDocumentsDirectory()).path;
    final file = File("$dirPath/${DateTime.now()}.pdf");
    if (!file.existsSync()) {
      file.createSync(recursive: false);
    }
    await file.writeAsBytes(await pdf.save());

Expected behavior expect the pdf file can display Chinese text.
