如何在Excel 2010中使用VBA查询UTF-8编码的CSV文件？

Question

我想在Excel 2010中使用VBA通过以下数据库连接查询UTF-8编码的CSV文件：

provider=Microsoft.Jet.OLEDB.4.0;;data source='xyz';Extended Properties="text;HDR=Yes;FMT=Delimited(,);CharacterSet=65001"

所有CSV文件均以BOM \ xEF \ xBB \ xBF和标题行开头。某种程度上BOM无法正确识别，并且第一列标题被读取为“？header_name”，即，带问号。我尝试了不同的CharacterSet，也尝试使用了Microsoft.ACE.OLEDB.12.0，但是到目前为止，一切都没有成功。

这是一个已知的错误，还是可以在不更改源文件编码的情况下获取正确的第一列标题名称的方法？

以下过程将整个CSV文件提取到一个新文件中Sheet，BOM从标题中清除该文件。它具有路径，文件名和BOM表字符串作为变量，以提供灵活性。

使用此过程调用查询过程

Sub Qry_Csv_Utf8()
Const kFile As String = "UTF8 .csv"
Const kPath As String = "D:\StackOverFlow\Temp\"
Const kBOM As String = "\xEF\xBB\xBF"
    Call Ado_Qry_Csv(kPath, kFile, kBOM)
End Sub

这是查询过程

Sub Ado_Qry_Csv(sPath As String, sFile As String, sBOM As String)
Dim Wsh As Worksheet
Dim AdoConnect As ADODB.Connection
Dim AdoRcrdSet As ADODB.Recordset
Dim i As Integer

    Rem Add New Sheet - Select option required
    'With ThisWorkbook           'Use this if procedure is resident in workbook receiving csv data
    'With Workbooks(WbkName)     'Use this if procedure is not in workbook receiving csv data
    With ActiveWorkbook         'I used this for testing purposes
        Set Wsh = .Sheets.Add(After:=.Sheets(.Sheets.Count))
        'Wsh.Name = NewSheetName        'rename new Sheet
    End With

    Set AdoConnect = New ADODB.Connection
    AdoConnect.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
        "Data Source=" & sPath & ";" & _
        "Extended Properties='text;HDR=Yes;FMT=Delimited(,);CharacterSet=65001'"

    Set AdoRcrdSet = New ADODB.Recordset
    AdoRcrdSet.Open Source:="SELECT * FROM [" & sFile & "]", _
        ActiveConnection:=AdoConnect, _
        CursorType:=adOpenDynamic, _
        LockType:=adLockReadOnly, _
        Options:=adCmdText

    Rem Enter Csv Records in Worksheet
    For i = 0 To -1 + AdoRcrdSet.Fields.Count
        Wsh.Cells(1, 1 + i).Value = _
            WorksheetFunction.Substitute(AdoRcrdSet.Fields(i).Name, sBOM, "")
    Next
    Wsh.Cells(2, 1).CopyFromRecordset AdoRcrdSet

End Sub
