FIX: SAX MSXMLWriter Fails to Save Characters Under Certain Encoding

When you call the parse or parseURL methods of the SAXXMLReader to parse XML data that contains characters that cannot be represented in the output encoding of the Simple API for XML (SAX) MSXMLWriter, you receive the following error message: For example, the error message occurs when the XML data contains the characters &#B9 FA; &#E1 BB; in GB2312 encoding while the output encoding for the SAX MSXMLWriter is set to ISO-8859-1.

The XML data contains a character that cannot be represented in the ISO-8859-1 character set.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

This bug was corrected in Microsoft XML 3.0 Service Pack 1.

Steps to Reproduce Behavior

1. Create the test XML document. To do this, download the Gb2312.xml file and move the file to the root folder of drive C.
2. Create the test project:
   1. In Microsoft Visual Basic, create a new Standard EXE project. Form1 is created by default.
   2. On the Project menu, click to select References, and then select Microsoft ActiveX Data Objects 2.6 Library and Microsoft XML, v3.0.
   3. Add a CommandButton to Form1. Command1 is added by default.
   4. Paste the following code into the Click() event for Command1:

      Private Sub Command1_Click()
          
          Dim writer As New MXXMLWriter30
          Dim reader As New SAXXMLReader30
          Dim adoStr As New ADODB.Stream
             
          adoStr.Type = adTypeBinary
          adoStr.Open
      
          writer.output = adoStr
          writer.encoding = "iso-8859-1"
                   
          On Error GoTo ErrHandler
                 
          Set reader.contentHandler = writer
          
          reader.parseURL "c:\gb2312.xml"
          Debug.Print adoStr.Size
          
          Set writer = Nothing
          Set reader = Nothing
          Set adoStr = Nothing
      
          Exit Sub
          
      ErrHandler:
          MsgBox Err.Description & Err.Number
      End Sub
      						

3. Test:
   1. Press the F5 key to run the Visual Basic project.
   2. Click the CommandButton, and note that you receive the following error message:
      Unable to save character to 'iso-8859-1' encoding. -2147467259
