VB Inet获取UTF-8编码的网页乱码

转化一下就可以，以下代码测试通过：
Private Declare Function MultiByteToWideChar Lib "kernel32" (ByVal CodePage As Long, ByVal dwFlags As Long, ByVal lpMultiByteStr As Long, ByVal cchMultiByte As Long, ByVal lpWideCharStr As Long, ByVal cchWideChar As Long) As Long
Private Const CP_UTF8 = 65001
Private Function Utf8ToUnicode(ByRef Utf() As Byte) As String
    Dim lRet As Long
    Dim lLength As Long
    Dim lBufferSize As Long
    lLength = UBound(Utf) - LBound(Utf) + 1
    If lLength <= 0 Then Exit Function
    lBufferSize = lLength * 2
    Utf8ToUnicode = String$(lBufferSize, Chr(0))
    lRet = MultiByteToWideChar(CP_UTF8, 0, VarPtr(Utf(0)), lLength, StrPtr(Utf8ToUnicode), lBufferSize)
    If lRet <> 0 Then
        Utf8ToUnicode = Left(Utf8ToUnicode, lRet)
    Else
        Utf8ToUnicode = ""
End If
End Function
Private Sub Command1_Click()
    Dim aa() As Byte
    Dim t As String, t1 As String, t2 As String
    aa = Inet1.OpenURL(Text1.Text, icByteArray)      'URL在Text1里输入
    If IsUTF8(aa) Then
        t = Utf8ToUnicode(aa)
    Else
        t = StrConv(aa, vbUnicode)
End If
    t1 = InStr(t, "")
    Text2.Text = Mid(t, t1, t2 - t1)
End Sub
