如何使用VB.NET显示注册商标符号（®）？

Question

我已经接管支持在该公司工作我的申请。突然之间，客户希望能够在栏中输入的注册商标。符号，用ALT + 0174，被正确保存，但应用无法正常对其进行编码。本质上，这是我在做什么：

    Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
    Dim ms As New MemoryStream
    Dim xml_text_writer As New XmlTextWriter(ms, _
        System.Text.Encoding.UTF8)

    xml_text_writer.Formatting = Formatting.Indented
    xml_text_writer.Indentation = 4

    xml_text_writer.WriteStartDocument(True)
    xml_text_writer.WriteStartElement("Employees")

    MakeEmployee(xml_text_writer, txtFName.Text, txtLName.Text, 11111)

    xml_text_writer.WriteEndElement()
    xml_text_writer.WriteEndDocument()
    xml_text_writer.Flush()

    ms.Flush()
    ms.Position = 0
    Dim b(CInt(ms.Length) - 1) As Byte
    ms.Read(b, 0, CInt(ms.Length))
    ms.Close()

    Dim strReturn As String = System.Text.ASCIIEncoding.ASCII.GetString(b)
    If strReturn.StartsWith("???", StringComparison.CurrentCultureIgnoreCase) Then
        strReturn = strReturn.Substring(3)
    End If

    txtName.Text = strReturn

End Sub

Private Sub MakeEmployee(ByVal xml_text_writer As  _
XmlTextWriter, ByVal first_name As String, ByVal _
last_name As String, ByVal emp_id As Integer)
    xml_text_writer.WriteStartElement("Employee")

    xml_text_writer.WriteStartElement("FirstName")
    xml_text_writer.WriteString(first_name)
    xml_text_writer.WriteEndElement()

    xml_text_writer.WriteStartElement("LastName")
    xml_text_writer.WriteString(last_name)
    xml_text_writer.WriteEndElement()

    xml_text_writer.WriteStartElement("EmployeeId")
    xml_text_writer.WriteString(emp_id.ToString)
    xml_text_writer.WriteEndElement()

    xml_text_writer.WriteEndElement()
End Sub

我从这个代码得到的输出是这样的：

             约翰         史密斯？         11111     

一切都很好，除了“??”之后，“史密斯”应为“®”。什么是最好的方式，如果有，以正确显示符号？

昏暗strReturn作为字符串= System.Text.ASCIIEncoding.ASCII.GetString（b）中

您编码UTF-8的XML，不读回为ASCII。你会失去所有不能被编码的特殊字符。修正：

Dim strReturn As String = System.Text.Encoding.UTF8.GetString(b)
