问题可能是你实际上并不发送编码为utf-8。它可能在Ansi或任何字符串/文件编码使用。然后它将不能在ASCII码中使用高于127的字符。您确定原始文本流是utf-8吗？你是否尝试过像其他iso- *格式的其他编码？

I am using Microsoft.XMLHTTP via VBA to pull in the body of a web page. In doing so, characters such as é get replaced with "?" or something equally not useful.

Here's the basic code:

Set objHTTP = CreateObject("Microsoft.XMLHTTP")

objHTTP.Open "GET", ThisWebPage, False
objHTTP.setRequestHeader "Content-Type", _
      "application/x-www-form-urlencoded; charset=UTF-8"
objHTTP.Send ("")

strResponse = objHTTP.responseText

Is there any way to retrieve the page with the special characters intact?

Note: I have also tried using this request header with no success:
objHTTP.setRequestHeader "Content-Type", "content=text/html; charset=iso-8859-1"

Thanks in advance.

Solution
Thanks to Ben.Vineyard (and some cursory Googling), I'm able to pull accented characters with the following code:

 ' Create the XMLHTTP object
  Set objHTTP = CreateObject("Microsoft.XMLHTTP")

 ' Send the request
 objHTTP.Open "GET", WhatWebPage, False
 objHTTP.Send ("")

 Dim BinaryStream
 Set BinaryStream = CreateObject("ADODB.Stream")

 With BinaryStream
    .Type = adTypeBinary
    .Open
    .Write objHTTP.ResponseBody

    'Change stream type To binary
    .Position = 0
    .Type = adTypeText

    'Specify charset For the source text (unicode) data.
    .Charset = "iso-8859-1"

    'Open the stream And get binary data from the object
    strResponse = .ReadText
End With

The problem could be that you do not actually send the data encoded as utf-8. It might be in Ansi or whatever string/file encoding you use. And then it will not be able to use characters high than 127 in the ASCII code. Are you sure that the original text stream is utf-8? Have you tried other encoding like one of the iso-* formats?
